I am trying to use a ZTE AC2726 modem with Android 4 (Zenithink C91 and Ainol Novo 7 Elf). I can enter the APN settings but not save them on both tablets.
Has anybody else experienced the same problem or even better has somebody found a solution?
Any help would be greatly appreciated.
I have same problem with Acho C906 tablet pc
Actually untill and unless the network is detected you can not save the apn .
Check the activity in terminal using radio command if the network is detected or not.

Hi Ferrum
Hmmm I have gone through a few 3G modem since I wrote that post and lets just get real here. Android and 3G is not a straight forward thing.
When you read the specs most Tablets say that they support 3G dongles. Most of them are in fact telling the truth but some of them don't tell which dongles they support. So you receive this sexy little thing in the post and want to connect it to the Internet and ......
After too many trials and errors here is what I found.
There is no golden rule about which modems works with which tablet. I at least have modems that works with one tablet and not with another.
If you want to be sure that a modem works then you should buy the modem where you buy the tablet (and make sure they guarantee that it work)
The following modems works with most Tablets (some of them with all tablets that I have tried)
Huawei E220
Huawei 1750E
Huawei 156G
Huawei E173 (not all versions)
ZTE MF637U
Based on the manufacturers specs Huawei 1750E seems to be the safest choice.
Even when you have a modem that is recognized by the tablet you might have to configure it which has it own challenges.
An easy way to overcome the problem with 3G dongles is to buy a Tablet with built in SIM slot like the W1107. You still need to configure it but you are sure it works on all networks and you don't have to carry a dongle.
When everything is done you have the freedom to access the Internet from everywhere (where there is 3G coverage), but there are a few hurdles that you need to deal with first.
One solution that I stumbled over today is MiFi. There was a nice article about this in the March issue of IT-Depot's Android Newsletter.
Seems to be a great way to connect all you devices to one 3G Bundle. In Kenya the unlimited 3G bundles are quite affordable so if I can share one 3G dongle with all my devices I will not only resolve the issue with Android and 3G dongles once and for all but also save money on my Internet Connections.

Hi All.
I've had an X10 mini pro on T-Mobile UK for nearly a year, and love it, but I am faced with a problem:
At work, I get absoluteley no signal. However, there are Wifi networks everywhere that are freeley available. It seemed logical to me that I aught to be able to get my phone to use those wifi networks to obtain a signal, so I did some research and found this generally to be reffered to as UMA (Unliceneced Mobile Access?)
For anyone who's coming across this technology for the first time, this is a facility which allows your mobile phone to use wifi connections as a backup for service signal, and switch seemlessley between them for use on calls (through your regular phone number [NOT VOIP!]) and texts.
I've read a lot of conflicting oppinions and statements on this, and wanted to ask here (In a place of expert knowledge and understanding) what the real truth is behind all this.
1: Is UMA a hardware or software based tool?
-I've heared numerous statements on this, including:
a) "Your phone can not do this if you don't have the correct hardware"
b) "The standard hardware (provided you have wifi access) is all you need, only the software needs to allow support"
C) "You need sufficient wifi technology AND the correct software to enable this"
Which is true?
2: "Service Providers are holding back on UMA support as it removes their justification for charging the user for calls"
- I've seen this in a few places, but it doesn't make sense to me. Sureley, despite the fact that the call is connected by a wifi signal, it still needs to find its way through a telephone exchange. Telephone exchanges cost money to maintain and manage, so that can't be right? can it?
- If anything, sureley this would give service providers a competative advantage as they can guarentee better signal coverage. It would seem more logical to me that the issue is less with the hand set, but with the providers managing the incoming and outgoing call data via the wifi network?
3: "UMA is/isn't supportend on android version X.X"?
- Again, I've seen conflicting info on this. What's the score?
Thought this was the right place to discuss all this and find the real truth behind UMA. My final question of course being:
4: Is there a UMA app or method by which I can use wifi as a signal backup? If not, is anyone looking into it and how soon may users see the benefits?
Appreciate any light that can be shead on this to dispurse the smoke and mirrors that seenm to surround it.
Thanks,
Oliver
hmmm
Supprised noone's responded to this... did I miss something?
In the USA, T-mobile has an app that does this. T-mobile USA uses the term wi-fi calling.
Is there such a thing in the UK? I know that the Optimus T (essentially the same as Optimus One) has this ability. I found this list of phones that work with this feature on T-mobile USA.
Phones that can make use of this new feature:
Blackberry 8520
Blackberry Bold 9780
Samsung Vibrant (SGH-T959)
Samsung Vibrant II (Galaxy S 4G)
LG Optimus T
myTouch 3G Slide
myTouch 4G
Motorola Defy
Motorola Cliq 2
Motorola Cliq XT
Sidekick 4G
G2
G2X
Nokia Astound (C7-00)
Nokia Mode (E73)
Samsung t339
Some other older android phones can work as long as the app has been ported for the device. Very YMMV

I do not think your phone is available through T-mobile USA, so it is not on the list. Someone figured out how to bring wi-fi calling to non-tmobile Roms for the Optimus T/Optimus One phone. http://forum.xda-developers.com/showthread.php?t=1116268 However, I am fairly certain that this type of app needs the cooperation of your carrier to work.

Try this solution, T-Mobile and Orange have done a deal where they can use eachothers signals, go back to netwoork settings and you should find " T-Mobile-Orange 3G"... Connect to that and it may work.
It seems that T-Mobile and Orange both have very bad coverage compared to other competators.
I'm in Japan for this year and I've just purchased a B-Mobile Free Data Sim (with voice), and while I can use the phone service, I can't use Data. After looking at b-mobile's GUARANTEED to work devices (bmobile.ne.jp/english/devices.html) other versions of the Galaxy S2 are listed, but not the i9100. However, in the list of acceptable bands, the following is written:
"Your device must support one of the following frequency
LTE Band 1 (2100MHz), Band 19 (800MHz), Band 21 (1500MHz)
W-CDMA/HSDPA/HSUPA Band 1 (2100MHz), Band 19 (800MHz)"
My Galaxy i9100T (From Vodaphone) should, as far as I know, support the W-CDMA Band 1 (2100MHz), but nonetheless, I can't use data.
I've made sure my APN settings are 100% correct, as according to the bmobile website.
Should I give up on trying to make this work, or is there some way I can get this going? Is there a particular radio or modem I can flash in order to get better connectivity? Otherwise I'm planning on buying a second hand Galaxy SC-02C or something which is on the list of devices guaranteed to work and relatively inexpensive. If you are knowledgeable on this subject, please lend a hand.
If there's any other information you require about my phone, please let me know.
Cheers
To the best of my knowledge, the phone wasn't sold there by carriers (neither the I9100 or the T), so there's no stock roms released by carriers in the country, and no modems bundled with those stock roms which would have been tested with the carrier's network as would normally be the case.
Sooo....You're probably stuck with trying a bunch of different modems unless a search throws up someone who's posted saying they had good connectivity with whatever modem on that network. If it was me, given the other relatively cheap option you mentioned (and my lack of patience with this sort of thing these days), I'd be buying the other phone if having a working phone without fuss was important to me (which it is).
Cheers,
I managed to get it working, on a stroke of luck. Flashing a few different modems didn't seem to get it connected, but after looking more extensively through the japanese version of the site, i found this page (bmobile.ne.jp/devices/setting_other_androidos.html) which suggested an alternative server to connect to for the APN (dm.jplat.net instead of mobile.ne.jp), even though this is the only page it seems to have this alternative server listed on. My reception isn't amazing, so maybe I'll continue as you suggested, flashing modems, until I can get better reception. Thanks for your help .
Anyway, for anyone who happens to have a similar problem, please try connecting to the above server and see if it works for you.
Hi clever android folks
needing some help..
I buy a year ago from dx.com a tablet called Vido mini 3G,,, its been really good tablet once I got it rooted and
xposed added etc
but this week I decide to try its hotspot feature since our home wan went down and had to switch to 3g and
wanted to share same SIM card data package with other devices like win8 and other androids
the hotspot aka wifi tethering just fails. it connects but stuck on obtaining ip and if manually give a ip it says connects
but no throughput happens.
has anyone got one of these tablets with JB 4.2.2 image from 20131119
and had same problem and found a solution
i suspect kernel or firmware issue.. like bad wlan driver??
the USB tethering works fine though
or better still is there a custom rom for this model I see a few for kitkat for vido N70 but I dont think its
the same hardware.
I'm sorry if this wasn't in the right area, I googled up this same question and this board has it the most it seems. If its in the wrong area, please move the topic to the right area so I know where to ask next tome (or link and I'll delete this ((if possible)) and recreate).
I've been using PDANet USB Tethering for the last 3 years or so with Boost Mobile, Samsung Galaxy S3. My phone is showing severe signs of age and issues, and I'm having tons of PDANet related issues. I have unlimited 4G LTE data, but I can't use my wireless tether because the phone company detects it and stops it at 8GB where as USB tethering I've gotten 100+ GB in a single month no issues.
I'm looking for a new phone I can get, that I can somehow mask everything I do on it so that the phone company is unable to see what I'm doing on it, and won't be able to determine if I'm using my phone's wireless tethering features. I prefer a smartphone, obviously, cause I do take it with me where I go and like to have access to my apps. I'm inexperienced with installing ROMs or rooting, never figured out how with my S3 because all the topics are outdated and inaccurate and I only ended up damaging the phone trying. I've got about a week or two to find a new phone that will work with Boost Mobile. My current phone's network mode is CDMA/LTE/EVDO, just to give you an idea of what network I'd need to use for Boost (CDMA I guess?). I need 4G as well, it seems that 3G doesn't work at all at my location and I only get 1 bar of 4G LTE when I'm at home in a specific 3 inch by 3 inch space in my room that I have to tape my phone down to, but at least it works.
There's no other internet options available to me where I live, so my phone is my internet. Just to clarify before people suggest getting an internet service.
Just to be sure, I don't want anything made by Apple, but that should be obvious, posting in the Android forum.
I have found that Boost Mobile won't let me use anything but like 6 specific phones only. Two of the choices being the S7 and the S8.
I've done a search on Amazon looking for unlocked S8 phones, however the comments and reports all claim these unlocked devices are a lie and don't actually work with services they claim to, or have conflicting reports and such. I'm unable to find an Unlocked S8 for use with Boost Mobile.
I've found that I can edit the APN to add 'dun' to my type list, to bypass the data limit of Mobile Hotspot, however I am hoping that it doesn't also cause the company to start charging me hundreds of dollars a month. I want to make sure they can't actually see the traffic either, I don't want my ISP knowing what I'm doing online, because they will just turn around and sell every website I visit to third parties which is now a thing in the USA.
I'd rather Boost not know whats installed on my phone or what websites I visit.
Thread closed as per OP request.
Okay, so you guys probably already found this:
Software binaries for AOSP Android 12.0 – Kernel 5.4 – Sagami (v1) - Sony Developer World
developer.sony.com
My question is if that could work with the newest update to enable wifi calling with T-Mobile in USA? I love this phone, but I have to get wifi calling to work properly like all my other phones do. I live in the mountains using starling internet and the digits app is unreliable for me but wifi calling works great. I saw a Reddit thread saying that installing the developer binaries on an Xperia 1 II allowed the the wifi calling to be turned on.
Any help toward this goal would be greatly appreciated! Thank you.
And I am posting this from an Xperia 1 III running the 61.1.A.7.35 firmware all stock.
Which Variant do you have I bought mine from Amazon but I flashed the SEA firmware and have VOLTE turned on but can't find WiFi calling
Okay after scouring Reddit I found this:
Came across this 9 months later while searching for a resolution to VoWIFI.
Google Fi WiFi calling works on all Android phones, because they don't rely on network-provided VoWiFi. Instead they redirect calls directly within the Android phone subsystem.
AT&T and Verizon enable VoWiFi only on supported devices. T-Mobile VoWiFi should work with any compatible device (and *does* work with the Xperia 1 series if you flash Sony's developer firmware on it), but in the production firmware this seems to be disabled by Sony.
End quote.
So...that's probably why...
Mine is the North America build. I don't need much from this phone, just working calls, texts and internet for business purposes. No android pay or special stuff. So if the developer binaries could make wifi calling work, it is worth a shot.
XQ-BC62 is the variant.
So if anyone could point me in the direction of how best to install the devoloper binaries, I will give it a go. It has been many years since I have done custom roms, adb & rooting type of funtivities on my old motorolas, so I am sure there are a few things different with this Sony that I want to do correctly.
Thank you!

Lol I've been out of the game since I sold my LG V40 just to be told my Galaxy S10 wasn't rootable since it was a snapdragon variant .-.
So the final working solution turned out to be the round Starlink dish that came with one ethernet port, which feeds into wan port of TP-LINK AX4400 with updated firmware, then feeding into T-mobile personal cellspot via DMZ ethernet port. It took a few hours of blinking lights for the background setup time on the cellspot to download updates but it works fine now with all green lights.
Still no wifi calling, but everything else works like it does in town, including calls through the cellspot without flashing or rooting, so good enough.
That's good to hear my guy
