This has started to happen recently. I am with AT&T Wireless in Brooklyn, NY. The phone used to carry the signal around almost the whole day and never lose it, but these days if I leave it alone for a while and come back it may say "no service" or "searching..." . If I do a soft reset it may find the signal, or if I turn wireless off and then on (which doesn't always respond, by the way -- on my phone it's called "Turn on Flight Mode". Is that what it's supposed to be called?)
I got this phone two months ago and I am extremely thrilled with it. It's a phone, pocket pc and (video!) camera in one. Sometimes it can achieve great clarity on conversations.
I wish someone can help me out though with some advice or information on upgrading the phone. I have the following questions:
1) What GSM frequencies does this phone use? Can I make it work with AT&T's 850 band? Is anyone familiar with making this phone work better with AT&T wireless?
2) What are some of the icons I see on the top, such as the G in a square? On my old phone that used to mean GPRS connection (i.e. internet/wap). I don't know how to control these things. To turn wireless off, I click a link that says "Turn on flight mode."
3) Finally, what can I do to stop losing the signal?? I tried putting manual selection of the AT&T Wireless network on, and it didn't improve things -- the phone still lost the connection. Once it had the connection thoguh, it didn't drop it -- I don't know why the connection gets lost.
Thanks a bunch for any advice and info,
Greg
Egreg,
I have similar problems. My provider uses GSM 1900 & 850.
1) It uses GSM 900/1800/1900. Unfortunately doesn't have an 850 radio; which is really bad, they should have made it a Quad Band for the price we pay for it. GSM 1900 is really terrible in buildings etc.
2) G Means the radio has negotiated GPRS availability.
3) I've gotten better results with signal locking on by following this thread:
http://forum.xda-developers.com/viewtopic.php?t=7619&highlight=signal
Download the application and set it to "Search GPRS on start GPRS connection". That way it doesn't have to negotiate for GPRS unless you actually want to use it (helps to establish signal lock much better as there is less protocol overhead).
Also now, I'm using Radio Version 1.06 & 1.08 as they seem to reconnect much better than 1.14.
Hope this helps.. Mine is performing much better now, not perfect, but not as annoying.
Thanks. I'll download the GPRS tweak program. Will that alone help the situation a bit? All I need is the voice capability, I won't use GPRS, only the GSM voice -- for internet browsing I may get a WiFi SDIO card from SanDisk.
I thought that changing to some other Radio software would help, but I heard on this site that changing the OS is risky. Can you tell me what I could do to get some a better connection, perhaps guide me through installing a correct version of Radio?
I haven't had this phone for very long, so I'm unsure if I should attempt to upgrade/downgrade.
-Greg
Greg,
I think the tweak program will help things a bit.. As I mentioned I am able to get signal seemingly quicker when I have it set...
I was pretty paranoid about OS upgrades, but I've gone through about 4 versions so far. This week is the first time I ventured out to use a different radio version than what comes with the upgrade.
Try the tweak and see how things go for a while, and then make your decision to upgrade your ROM...
Hello dear XDA members !
I'm an happy owner of a Transformer (dock, 16Gb) and my uncle who tried out yesterday is now planning on ordering one for him. But his main purpose would be to use it with a 3G dongle... Would it be possible, even with some tweaking ?
Thanks a lot in advance for your kind and hopefully positive answers
Either use a phone with 3G capability and tether via bluetooth or get a Mifi you can use with a 3G sim card. The USB dongles will not work as they require drivers.
Im no expert but would this be of any help to us Transformer users?
I think it must be possible, I just do not know how. Because there is a mini-pcie position inside the tablet, and it is labelled 3G on the motherboard.
3G hardware will be installed by Asus at some point in the future. So, the software has to support this 3G. It might be easier (or harder) to get the software to recognize a 3G dongle, but I wonder how.
Great thread.
Hello,
(sorry for my bad english)
I would like to use this thread for trying to connect and use my 3G dongle on the TF101.
It's a patch for using some 3G dongles with ACER A500.
Maybe we can use it for TF101 too?
Well... I just want to try on my TF101.
So I've compared files from A500 with files inside the Prime! v1.5 rom.
I've kept some files and replaced others with the new one. But there is a file that I'm not sure:
- rild
I think it's the Radio Interface Layer Daemon or somethink like that.
From the A500 patch, "rild" file contains only text lines like this:
Code:
#!/system/bin/sh
insmod /system/vendor/lib/usb_wwan.ko
insmod /system/vendor/lib/option.ko
chmod 777 /dev/ttyUSB0
chmod 777 /dev/ttyUSB1
chmod 777 /dev/ttyUSB2
exec /system/bin/rild.run [email protected]
size: only 1ko
From the Prime! rom, rild file seems to be compiled:
Code:
ELF
size: 10ko
So I wonder if I can replace the file or not without bricking my TF101.
Does someone know this file and may advise me?
Regards,
Kasi
EDIT: Done but no 3G and no Mobile Network option
I use a 3g router. This exact one as a matter of fact. Works awesome and has many other perks such as battery and availability to share the 3g with anyone. I no longer care if the tablet ever supports the 3g modems. I am up and running and happy!
MBK
yes indeed. It works with a 3G router, and by thethering with my Android Phone too.
But in this case TV from my Mobile service provider doesn't work. So I must have my 3G dongle directly connected to the tablet.
I f you can't use your phone as a 3g hotspot eg. blackberry and you don't want to use a portable hotspot like a mifi and you really want a 3g dongle I recommend getting a sapido mb1132 - sorry can't post the link yet new forum user.
You can use it with your 3G/4G dongle or with an ethernet point or just as a range extender about ¬$80 off ebay.You can even use your phone as the data source. just google Sapido the products 3g/4g
I use my Sensation and a MiFi as mobile hotspot. No mod, no hack, no worry about breaking the usb dongle, no worry about the battery life because the usb dongle use a lot of power from the usb port.
Hey, I just found another option for remote internet access, although very similar to the mi-fi already mentioned. I got a Clear Rover Puck portable 4G hotspot. I tried it a few places, work, home, friends house, various parking lots and businesses, and it works great. It is very small and light, so I carry it in my pocket sometimes, and just get it out and turn on when I'm ready to surf. I'm a new customer. They give you 15 days to try it out. It's $35/month, although I think i saw somewhere that you can also use it for $5/day if you don't intend to use it that very much. Just google it and you'll find reviews and info. Also should check your 4G coverage area before buying.
http://www.clear.com/devices/details/id/93
I also bought that thingy from ASUS that allows you to use the bottom port on Transformer as a USB jack, which I guess you'd have to use with a dongle. I'd be afraid of breaking the port if using the dongle a lot, so that is one reason I like the standalone puck better. Also, You can connect several devices to it by wi-fi, not just 1, as with a dongle.
Hello,
I have a problem with my android tablett, with sim card slot.
In the mobile network settin, we can find this :
GSM/WCDMA (auto connect) - automatically switches between 2G/3G modes. When signal strength is low, 3G is favored more
GSM only - 2G only mode. When 2G signal strength is low, you get no data.
WCDMA only - 3G only mode. When 3G signal strength is low, you get no data.
But in my case, i can't switch to " GSM/WCDMA " or " WCDMA only ", it still changing in gsm only, when i change to " GSM/WCDMA " or " WCDMA only ", the setting goes automaticly in " GSM only ".
Is there a way to solve this problem please ?

If the tablet does not support the frequencies for 3g from the carrier / SIM card you are using, this behavior is normal. This is just the first thing I thought of, but without knowing the tablet model and carrier, there isn't a way to really know.
The tablet comes from China, it's a MTK model, but the website says that the tablet is 3G built-in and that they have tested all the tablet before shippement ....

Just because a tablet has 3G capabilities, does not mean it is compatible with 3G from everywhere. There are different frequencies and bands that each carrier have. Imagine them like radio stations. Your favorite radio might be all new and shiny and able to get all your favorite music on your favorite channel like 101.3 FM, but maybe you also like 700 AM, but though there is nothing wrong with your radio, it might not have settings to connect to AM stations. So you can't listen to 700 AM. Just like if your tablet supports 3G on the 900/2100 frequencies, but you are using a carrier who's signal works on 850 and/or 1900, then you are out of luck.
Ok thanks for your information ! It's surely because of that, because the China seller says me that the 3G work in their office, but not in my country !
My tablet is a phablet, i can call ans send sms (these functions work without problems), but if i buy a 3G usb dongle for the tablet with all the WCDMA band and if i put my SIM card into this dongle, i will be able to have 3g internet connexion AND be able to call and send SMS also ?
Most likely that will work as long as the USB dongle supports the frequencies of the carrier. If you post the model and carrier I might be able to provide some less generic info.

Thanks, your generic answers is already helpful :good:
So the dongle can simulate an other SIM port with all the mobile functions, but the difference is that i could have 3G network !
My tablet is a MTK6577 and my mobile operator is Orange (France)
Hmm According to the info I found on quite a few sites, Orange (France) uses the 900 and 2100 frequencies for 3G, which I think most of the Chinese tablets and dongles I have seen support that... So you should be fine. I thought at first that the tablet has built in 3g, but thinking about it now, the 3g is ONLY supported by the dongle probably, right?

The seller says me before to buy and again now tht the tablet have 3g built-in, but i'm not sure if the seller says the true or not !
I have downloaded " Mobile uncle tools " and then i went to the " band option " and i can select ALL the GSM band but all the UMTS band ( WCDMA / 3G ) are not available
Yea, that's why I was wondering, because many of the lower priced tablets don't have it built-in (though plenty do, which makes it more difficult since many do not have much documentation on specs and brand names). So this means 1 of 3 things:
1) Seller does not understand the difference between built-in and the dongle - possible language barrier?
2) Seller is lying to you, hoping you will say screw it and buy the dongle.
3) There is something wrong with the tablet.
I hope it is #1 for your sake. My guess is #2. Number #3 doesn't seem likely since the Settings aren't working to change either and it's not showing up in the other tool, which is a well known tool that works for most MTK devices.

I'm thinking that the seller lie to me, i have opened a disput on the website, and i will have to proove what i'm saying ! ( that the tablet is not 3G built-in, i can upload picture and video on the disput webpage of the website )
But the tablet works in 2G mode without problem, so with a 3g dongle it can solve this problem ?
I would think so, but I've never had much reason to look into dongles other than a passing - oh, they can do that...? Because most tablets sold in the States are going to have it built in or just for wifi only. I don't get many people bringing me these kinds of tablets to work on anymore for some reason, so haven't had much chance to play with them lately.
Side question: Do you have an android phone? It might be possible to set it up to tether from it to the tablet as well, depending on the phone, update, and carrier.
Yes i have an other android phone with 3G working on it !
Which phone and what software update does it have? You're using it with Orange as well?
It's an HTC wildfire S and it's android 2.3.2 !
Why ?
Hello, this is my first posting thread, but i need some serious help for my Asian LG H930DS (with Europe H930 Android 8.0 OS), i wanted to try solve 2 issues, from which 1st one wasn't that much important to me: hotspot not having option for choosing 5GHz, and always having slower wifi than it should be(using tp link archer ax20). For 1st issue, i was following instruction i found on this site:
https://www.reddit.com/r/lgv30/comments/kpsubf
,so basically i dialed *#546368#*930# for hidden menu, gone to Field Test -> WiFi Test -> OTA Setting, clicked enable and core both(i don't remember if it was already enabled or not, but i remember for core both being already ticked, wifi turned off when i clicked enable ota thing, hotspot wasn't working till restarted phone), not only it didn't help at all to get that 5GHz option in hotspot settings(which was always max giving wifi 4 n standard, checked in properties on laptop), but it somehow messed up to my wifi works worse and better at same time(will explain), neither restarting my phone helped to get everything like was before. Basically what happened is that on wifi, which was earlier always showing 866Mbps in settings, is now double reduced, now showing 433Mbps. Before i messed this up, i was always having wifi speed of around 150-160Mbps on speedtest with those 866 showed in settings, which is 2nd issue i mentioned that wanted to try fix as saw in some tp link forums people complaining about that lower speed on v30(yes i'm aware that my phone doesn't support wifi 6 ax standard which my router have, but it's still too small score for ac standard when i have 1Gbps internet). After i messed up, speedtest was surprisingly showing 250-260Mbps, but was also having big downfalls during testings and in end result was even more times showing just around 80Mbps, while earlier when was 150 weren't big jumps and falls during testings like now. On tp link site for settings router, for my phone was always showed Tx/Rx rate 866/6 , while now after messed up showing 325/433. Also noticed that now when restarting phone, in settings not showing up 5ghz wifis for 2 min or so, not big deal, but little detail i noticed, slower loading them now only after booting up phone. Sorry for longer text, i really hope someone can help me bring back how it was, to showing again those full 866 speed, no matter if speedtest shows "just" 150, but to be stable.
Is there any possible fix for this before i try with wiping out whole phone and restoring everything from backup? Will that help, or whole process will be useless?
Sorry, I don't have any better advice for you... sounds like you made some changes and things are weird now.
One thing to remember about wifi is that it's not always consistent anyway. Speeds reported by devices can change for MANY reasons. For example, distance from the AP, angle to the AP, interference from other APs, and many more. Using these numbers to say there is a problem is just going to make you crazy unless you are in a controlled environment.

Yes i'm aware for wifi not being consistent and all those factors affecting on wifi, in fact today was suprisingly stable 150-160 speed, but i can still see there's definitely some problem when is showed 433Mbps in settings instead of 866 like was earlier at same distance from router, and on tp site settings too for Tx/Rx rate being weird like said in text and showed on screenshots. In fact only my device from all other devices home have weird proportion to Rx(recieve) be bigger than Tx(transmit) and to showing Rx to be those "max" 433 which is wrong
I'm thinking that maybe having Europe OS in Asian device have to do something with that wifi modem problem, maybe i'm wrong, so not advicing anyone to toggling OTA settings. I'll still wait before i try that complete wiping out phone(not even factory reset), or will let it be, still undecidable for that, but thx for help, any help really appreciated!
Again, those readings are not very important and will vary often. Those are theoretical values based on the connection type. In the end, the actual speed you get is really all that matters. For example, my laptop is showing up in my router at speeds like 706, 702, and then suddenly 585. Sometimes it will show 866/6 as well... so a very asymmetric reading is possible. And I'm sitting about 10-feet with clear LOS to my router.
It's not meaningful to worry about those numbers. Unless you're having an actual speed problem, it's not worth worrying about those. There are way too many things that can affect those values (dynamic frequency changes in the router or the device, interference, power management things, etc... there's a TON going on behind the scenes. Just because your device or router says it's on that number for a moment doesn't mean that it won't ramp up when there is a need to do so (or ramp down when there isn't).
EDIT, there's a nice long explanation about the tech here, if you're interested: https://www.duckware.com/tech/wifi-in-the-us.html

Didn't read all from that site, but i saw for MIMO thing, and my phone(snap 835 specs says it) support that 2x2 MIMO with speed up to 866, but looks like you were right, not related to those showed numbers, i was getting good speeds of wifi. I still just now refurbished whole phone as i saw that battery is draining drastically faster after i messed up that wifi showing numbers, now when i put actual h930ds firmware in it(early oreo), and connected to wifi, i checked and saw those 866Mbps, so that thing is fixed, but not just that, i also saw in tethering hotspot that i now have option to choose 5GHz which wasn't there, from where i started all this mess at all. Now planned to put Europe H930 OS latest oreo back again to see if maybe that different OS have to do something with that not showing up 5GHz hotspot option, and on top of everything: to hope that battery was draining faster because of that wifi problem and not because of battery itself, as i have phone now for more than 3 years, which works like 1st day. Will tell results
Excellent, glad you got it figured out and back to working normally! Sorry I couldn't be of more help for actual steps, but you got it done, so great job!

You did help actually, as that site seems one of those rare ones which goes deep in explaining all about those connection stuffs for people like me who don't understand that much about it in details, and with today's standards with phones connections with reality of scores using WiFiAnalyzer and not some marketing bs, even if i didn't read all, i will as saw how well are explained and done tests, and also helped to realise that numbers showings don't seems to be reliable much(when it comes to those numbers from settings unlike on speedtest app). Also i just now refurbished phone again on that latest Europe Oreo OS, and seems like there's no 5GHz option available in hotspot, so to all people wondering about not having 5GHz tethering hotspot on their LG V30, it's because Europe restricted it (H930 Oreo OS, i don't know if that's case with Pie), it gives max wifi 4 n standard(again checked on laptop in properties for connected wifi hotspot from phone), it's same thing for recording fm radio, as on Europe OS there's not available that red button for recording it, while on Asian one there is on bottom right side. I'm thinking if i should use original H930DS Asian OS even if i'm in Europe, but i didn't see any benefits or downfalls when it comes to carriers here(didn't much travel to check for other countries in Europe, talking for my place), as it works for both OS everything, and can still have VoLTE i think? Will everything works fine in any Europe country carriers and stuffs? Or is there maybe bypassing this issue to get 5GHz hotspot on Europe OS by changing wifi settings launcher like appearing recording button on fm radio app is solved like that?
Glad that link helped. Yes, Wifi is rather complicated and the numbers we see on boxes and devices is rarely realistic or even attainable.
Beyond that, Wifi also has other issues... it's a nice system when it works, but it has a lot of issues in crowded areas. Here's an older article which talks about why Wifi kinda sucks, in general: https://arstechnica.com/information...hat-a-deep-dive-into-why-wi-fi-kind-of-sucks/
The key message there is that Wifi is shared, so if the router or device sees another device on the same channel, then it may be forced to wait, thereby reducing the bandwidth you'll see. A lot of people don't realize that. Heck, in the older days, wifi would only run as fast as the slowest device... which was even worse!
Again, glad to hear you're working well. Interesting that the 5GHz is not available on the European OS. I don't know enough about that situation, so I won't be able to help there. Generally speaking, I would recommend seeing if you an use the US998 firmware, which is the USA "Global phone" ROM... this works well in the US on any carrier, but may also work well on foreign carriers. I expect hotspot 5GHz would work as well.
I don't know about VOLTE in foreign markets. I know that in some cases that doesn't work in the USA (AT&T is one carrier who is awful about this). In other carriers, you sometimes just need to use their ROM - that's what I did for my Verizon-based carrier (I used VS996 instead of US998). For your case, you may need to ask others or read here to see Europe-specific info. I'd love to see what you find, just for my info... I'm always curious!

I'm literally blown away what i discovered from all testings i done, i hope people will read this, without any offense to anyone, everyone who think/said in other threads and forums everywhere that is basically same if you put European H930 OS in Asian H930DS device like having stock H930DS OS are WRONG. Yes, it's true for both OS supporting same modems for carrier networks and stuffs, but it's obviously for reason made separate OS for different devices, i never imagined that would getting proper wifi speed of 450Mbps and 460 every time i tested(in settings for wifi of course showing theoretical 866 speed), after i put OS that belongs to my device originally, never going back on EU OS. When it comes to 5GHz hotspot, button is there, but when you select it instead of 2.4GHz, button for turning on and off hotspot doesn't work, it turns off same sec you toggle on, only way to make it works is by enabling OTA on same way i mentioned in first message(dialing *#546368#*930# going to Field Test -> WiFi Test -> OTA Setting etc), but when you enable it, then again happenes same thing from before, to wifi in settings showing 433 instead of 866 , and on speed test not anymore 450, but 250Mbps, which is still more than previously using EU OS. After enabling OTA, hotspot for 5GHz worked(details coming next), but when you restart phone, even if OTA stays enabled, hotspot button again doesn't want to toggle on with selected 5GHz, till you again dial number to just click "enable ota" , even if it's already enabled, which is weird, so every time have to click enable OTA after restarting phone in order to make 5GHz hotspot works. When i clicked to disable OTA, in settings for wifi wasn't showing anymore speed of 433, but was showing 520, 650 unlike on EU OS where even after disabling OTA was still staying those 433 as "max", but(always some but) even if it was showing those "theoretical" 520 and 650, on speed test was sometimes 250, sometimes 320 speed, not anymore those 450, so will again refurbish phone to that same OS, and don't recommending anyone to using those OTA settings, it's not worth it for 5GHz hotspot, reason i staying on that OS is because of compatibility of modem for wifi obviously, my carrier have full signal too like with EU OS. When it comes to VoLTE, i'll be able to check that when change carrier package soon.
So about 5GHz hotspot, it's not worth it, here's what i found out: when hotspot is sharing mobile provider data, then, and only then, is true 5GHz hotspot, but it gives speed around 150Mbps(all tested on laptop), i don't know if that's good or bad, as i honestly don't know what is speed of my mobile data provider. If i connect phone to 5GHz wifi to share that wifi through hotspot to laptop, even with enabled 5GHz for hotspot, then of course it's not true 5GHz hotspot as guessing that antenna is being used for wifi, so because of that, it's showed on laptop in properties that is 2.4GHz band with wifi 4 n standard, interestingly enough, in that situation lg put to hotspot gives just 1 channel, but strong one, and because of that, sharing 5GHz wifi on false 5GHz hotspot gave result of 100Mbps speed. For 2.4GHz hotspot, it's around 60Mbps no matter if sharing mobile data or wifi(no matter if wifi from 5GHz or from 2.4GHz).
Yes i'm aware all these are just numbers, i tested more times and got mostly all these same results, they still showed me big differences to see that there were definetly some wrong stuffs going on from phone and OS, so can't say that was maybe at that moment wifi itself interrupted or anything by other people here inside
Final verdict for people who can't reading all this: don't mixing OS with devices that not belongs to, in order to have way better modem wifi and carrier performance(still have to check for carrier one, but for now looks excellent), H930 and H930DS OS are NOT same when it comes to that, don't ever touch OTA settings, don't try to enable 5GHz hotspot on H930DS with OTA, not worth it at all, not much speed getting from it, H930 doesn't have 5GHz at all and don't trying to get it. Hope all this helps.
Here i am again with update, after restoring everything 3 days ago, i'm very happy about my whole phone, battery is excellent, wifi always being much more speed than i ever had earlier, carrier's 4g mobile data sign was appearing right away instead of waiting 5 sec or so. I'm writing this update to let people know that looks like you need to choose between performance of modem from phone(wifi and carrier network), and having VoLTE, as yesterday i changed carrier package which have VoLTE, and i didn't get it, neither can enable it using this very helpful tutorial, as i'm missing lot of files that Europe OS have: https://forum.xda-developers.com/t/module-v17-x-volte-vowifi-enabler-2018-09-20.3649613/ , i'll maybe try to include those missing system files in my Asian OS even if they belong to Europe OS so to try enable VoLTE that way, if that doesn't work, then i won't have it, as for me is more important wifi speed. Main problem here is to get IMS service be registered with Europe carrier on Asian OS, even if i see that there are indeed ims files available on Asian OS, so that maybe tells something, maybe someone find some workaround.
Edit: there's no way to enable or make work lg ims service on that specific AME OS for some reason, i just now (again) put Europe OS as want to see if i can have VoLTE at all, so don't mind me switching OS , but yes, i tested wifi, it's indeed reduced speed with that OS than original one.
