Hi everyone!!
Some time ago there was a discussion about data only sim cards (in Japan). Basically data only SIM doesn't connect to network like normal voice sim so the os boosts radio signal in search for that (non existing) signal. Then you have a huge battery drain and phone gets hotter.
Apparently the fix was some docomo sim patcher module for xposed. The module is removed if you search in xposed but it can be found online. In all discussion I dont see nobody mentioning kitkat, only ics and jb. I saw somewhere that this problem is supposed to be solved in kitkat but its not. In kit kat there is signal bars but cell standby is high and battery drain is huge. Have in mind that this happens exactly the same on various devices ( Im now on OnePlus one).
I installed the module, and it solved the cell standby (it used to be 100% and now is much less) but time on says as long as the actual time on of the device and although battery life is better it still drinks too much battery no matter if on LTE or 3G. Mostly i notice that battery drain is way too huge when cell phone is in stand by.
Did anyone finally got around this problem? Is there some up to date fix? All I found is very outdated, and no clear solution either.
Thanks
I guess the solution is to pay a little bit extra for sms function, that way phone should connect normally to network and I think there shouldn't be no problem. Somebody please confirm if you tested. Thank you.
So turns out that patch did fix part of the problem, but now here is another problem. Patch is a xposed module and as you all know ,xposed doesnt work in Lollipop.
What is the possible workaroud?
Is there any way to change the code so that phone doesnt look for network when sim is inserted?
I get signal bars but it says no service and in battery settings network signal is red (as if signal is terrible all the time while Im actually missing only 1 bar). When I set apn lte sign appears and internet works (along with huge battery drain)
I am currently in Japan and having the same problem on my Nexus 5 and Android 5.0.1. Is anyone having a solution by now?
Thanks, would help a lot if my phone isn´t discharged after half of the day...
Well, nexus 5 and battery are not best friends to begin with. I am also on Nexus 5 currently. The best bet is to activate sms option which is only 100yen more monthly, and that way phone should register to network probably. Only problem is you have to buy sim again (at least in my case with biglobe).
You can also toggle airplane mode every time you dont use internet ,thats what Im doing right now,although wont save that much.
Interesting thing is that I didnt have that problem with HTC's 4.1.2 jelly bean..
SMS chip doesn't help

I have a Nexus 4 (Android 5.0.1) and I bought one chip in BIC Camera with Line support, which means I can receive SMS (no voice). My battery is draining if the mobile network is on. The best thing I can do for now is, like you said, toggle airplane mode when I have a WiFi connection available and carry a power bank if I need to use 3G...
I have a Nexus 6P on Android 6.0.1 and use a data-only SIM card on Docomo's network in Japan (purchased from BIC camera). This issue has not been solved.
Some have claimed that a previous Android update from 4.x has solved the issue, but this is not the case. I've used multiple Android devices in Japan over the past 2 years with these "MVNO" SIM cards and every single one has the issue of battery drain. The iPhone does not have this problem.
Has anyone solved this? There was an Xposed Module fix for this, but that was ages ago and I presume it does not apply to Android 6.x.

Sorry, I've left Japan a year ago and don't have Nexus anymore too, so can't help much..
Any progress on this?
Has it been fixed in Nougat?
I hope so. Going to Japan again later this year. Was a pain on my LG G4 last year. Got myself a Nexus 6P now with Android 7.1.1.
Pure Nexus ROM 7.1.2, same battery drain...
I have 0sim, which is free up to 500MB.
I can't add SMS option, because it will cost money.
Please, anyone, post some solution on Nougat for data only SIM.
My phone is rooted, but still no Xposed for Nougat. If it was some tool...
Hello,
I'm losing my wits, hope you can help me..
My G2 mini (new) worked flawlessly for a couple of weeks, then suddenly lost all network signal. After a few days, thinking it was a software issue, i unlocked the bootloader, rooted the phone, and installed CM11. An hour later - full GSM signal. For a few hours.. Since then, i've been having random x hours with, y hours without GSM signal, with absolutely no reason for the changes (phone laying on the table, absolutely no user input).
It might very well be a hardware issue, but my google-fu failed me big time, all i seem to find are GPS issues (which is not the case here, especially since i don't need GPS on this particular device).
Here's a breakdown:
- The phone originally worked with no signal loss (original OS)
- Unlocked bootloader, rooted, installed CM11
- Signal works for a few hours every day (random pattern), loses it just as miraculously.
- Device finds no networks when using the in-built search functions, but i receive no error message. When using Automatic registration, the phone displays: "Can't connect to this network right now. Try again later".
- My SIM card works fine in my D802, same issues occur on the D620 with a different SIM card (which also works without fault in the D802), so it's definitely a phone issue.
Questions: Anyone have any idea what's going on? Could it be a baseband flaw? Is there a way to (re)install the baseband, to eliminate any possible software issues?
I have disassembled the case, and all pins have wear marks embedded, which means there's plenty of contact, as far as i can see.
Thanks in advance, guys!
I just toggle airplane mode on and off, this works with me I have the same issue on. cm12. Hit that thanks button if I helped you!

Unfortunately, my issue seems much more severe. Toggling the airplane mode, restarting the phone, nothing seems to work. It just regains the signal whenever it feels like it. For instance, it's been "off" for a few days now, with the exception of 2-3 hours a couple of days ago.
Thanks for your input, though!

With the latest release the problem disappeared. With previous releases I would open the phone sometimes and it wouldn't have any signal. I either had to restart it or toggle airplane mode on and off....

PS: The IMEI is correct
Greetings to all from a total newbie!
I just got an unlocked, dual sim Honor 5x and anytime I tether it or use the Hot Spot, the phone is completely isolated from the internet; it doesnt update my email and I cannot access any web service through the phone while it is in active Hot Spot or tethering mode. This did not (and still does not) happen with my old Blu nor with a Note 5 that I just tried.
Is there any not overly comicated way to change this, or must I change phones altogether?
Thanks to all!

try factory reset
If factory reset don't work, try to flash the system
Hello
I recently purchased this phone for a family member. We set it up yesterday, and found that the sim card from their old phone that we've inserted isn't capable of allowing the phone to make/receive texts/calls. It just says something along the lines of "Can't connect to mobile network", despite showing signal bars. When I checked the connectivity bands against the mobile network's, it appeared that the phone should at least support 2G & 3G. I'm in the UK and haven't modified the ROM.
Has anyone had this issue before, and does anyone know of a fix? I've heard that some of the newer official ROMs are better for connectivity, but I don't want to flash the phone and void its warranty if the fault lies with the phone.
Many thanks
Luke
Heyyo, hmm can you please provide more information?
Link to the exact product purchased
What country and network is being used?
Does your device say x820, x821, x822 or x829 on the back of it? If not does it say what it is in the settings > about phone menu?
Can you please specify which version of EUI ROM it is running? Should be in Settings > About Phone.
As for upgrading EUI ROM versions? That will not void warranty as long as you don't have the x829 with EUI ROM 5.8.016s.... which is what I had and x829 with 5.8.016s is garbage. So many darn problems with it and has software updates disabled even via recovery update.zip... I didn't stay on it long since LineageOS 13.0 at the time officially came to the x2 heh

This is where I ordered it from: LeTV LeEco Le Max 2 X820 5.7 inch 4GB RAM 32GB ROM Snapdragon 820 Quad core 4G Smartphone
I live in the UK and the phone's using a Tesco Mobile SIM
The device is the X820
I don't have the phone with me right now, but I believe the EUI is 18s
I wasn't aware upgrading the ROM version didn't affect the warranty, that's nice to know
Hallo,
I believe I might have the same problem with the mobile network. In my case, I am quite certain that the battery is the problem. I got the phone some weeks ago, but I assume it was laying around for quite some time, which might be not very beneficial for the battery? Anyway, the voltage should be 4.4 V after loading and as long as the voltage stays above about 4 V, I have good data connection. But after a while, the voltage drops below 4 V and I do not have any connection anymore, despite showing all signal bars! Is it possible, that you see a similar behavior with your phone? If you load it on a charger, does your data work?

I personally do not experience this but I'm 100% sure that the voltage from the battery should stay around 4V. If this happens try turning on the battery saver and dimmer your screen so you can spread the battery load. Maybe it will work idk.

You are probably right in saying that the voltage should stay around 4 V. This is probably the case for new or at least well aged batteries. However, that seems not to be the case of my battery. According to the App that reads out the voltage, it sometimes drops to values as low as 3.6 V. Sometimes, the voltage recovers a bit, but typically, not enough to enable data connection, for which I believe to need at least around 4 V to work (reliably!).

I purchased a X820 from China (TomTop.com) and the junk had an EXTREMELY LOW signal.I NEVER received network signal at home.I have to go near a cell tower to get signal,as soon i drive away from the tower (around 5 blocks)i lost signal and could not make or receive calls..Remember that the company LeEco went out of business and the phones we buy today are NOT made by LeEco but are made by many private factories in China and in reality are cheap clones.I send the junk back and purchased a X829.Now i have very good signal and connection never dropsJust return your phone is defective..Here is a video i had to send to tomtop.com in order to get a refund.

I have exactly the same problem when the phone's battery level goes around 70% (~4v).
i.e. when battery drops below 70%, the network signal shows LTE with around 3 bars but there's no network connectivity and can't make/receive phone call. But as soon as I plug in the charger, everything works perfectly! This happens on all ROMs.
I wish there is a solution for this.
same problem for me .....
Today ,
NO WAY to have working Network mobile on a Leeco LE 2 x526 with last stock rom 28s installed on it. NOW i can call on 3G but no voice ,,,,, but i can't be called. .....after restart with / without APN / searchable 3G/4G network Digi.Mobile ...signal is lost and is cost me allot of time and energy . i even lost any hope .....(coul be a hardware problem ?)

5.write lost IMEI
6.write new baseband with DFS
7.flash modems firmware (MPSS (56347 , 61295 , 66782 and 68083))
8.try other Carrier SIMS ..... same problem
9.check any carrier server service ...nope

I believe your phone is a X829. Someone installed the X820 firmware to sell it easier. It doesn't have Band 20 for 4G. Tesco mobile is working on O2 network and they're using Band 20 for 4G network. Despite that it should work on 3G. In my opinion you should install a custom ROM and check things there...

Solution: Disable "Dual 4G" option in the "SIM Cards & Mobile networks" settings
Hello, good day!
tl;dr: Phone stuck to no cellular signal, until I reboot, restart mobile radio power, or turning on airplane mode for a short while when turning off again.
---------------------------------------------------
I recently bought this phone as an upgrade to my old one. I transferred my sim, and all seems to be working pretty well. I lived in an area with very poor signal reception, so overnight, the phone doesn't have any signal reception other than WiFi.
The problem is that it remains that way (stuck on 'no signal') if it cannot get any signal for an extended period. The problem persists even if I went to an area with good cellular reception even in the city.
The problem seems to fix itself when I placed the phone either by activating airplane mode for a minute, turn off "mobile radio power" then back on again, or reboot my phone but it starts to get annoying over time.
I tried changing the preferred network type to the one my old phone used (LTE/CDMA auto (PRL)) to fix it, but no luck.
Does anyone know a permanent solution to this?

I tried the SIM Reset first and so far it is working perfectly but I need to monitor it first to check if the problem would persist in the long term.
Will update thread on the result.
================
Update: unfortunately, the SIM reset doesn't work. However, I tried swapping the SIM card to see if it makes any difference and surprisingly it did. I put in a SIM in slot 1 from a network with a good signal reception while my previous one on slot 2.
I would like to also note that the current SIM 1 has a successful Xiaomi activation & verified to use the chat features on the Messaging app while the old one does not.
All seems to work perfectly - but need further monitoring I can call it solved. Will update the thread on the result :good:
Update 2: The workaround above doesn't work. I sent to Xiaomi this issue.

My sim is in slot 1. still dropped calls. Seems like network disconnects and reconnects.
When call is dropped I immediately redial and sometimes no network.

Unfortunately, the workaround I posted doesn't seem to work also when my current SIM 1 can't pickup signal for at least 2-3 hours.
Yes I also experienced drop calls most notably when the signal drops below 0 bars (not no signal with an "X").
I can't find a good rationale a factory reset would solve the problem since nothing on my phone (modified settings, modded, or downloaded apps) that can affect the cellular network. So, I won't be taking that road for now.
I already sent feedback on Xiaomi and advice me to send the log files *fingers crossed*
Any updates..?
My father is experiencing similar experience with calls hang and even bad call quality, while pocophone f1 on the same network works flawlessly.
Data problem
I have a problem with my RedMi Note 9 Pro, when I make a call on 4G Airtel network(at least 4 bars) the data connection drops to an average g of 1.2kbps.
I have used the same Sim in the same area in my previous phone the Honor 9 Lite but it doesn't face any problem. Whenever I get a call on that phone the 4G data speed increases.
On the RedMi note 9 pro the data gets completely disconnected and even after I cut the call the data remains disconnected for 2 minutes or so. After that I resumes back. It even gets lesser speeds that my previous phone.
Sometimes the data drops without any reason. It stays disconnected for a minute or so and then tries to connect back. It has got horrible ping.
Anyone facing the same issues?
Having the same issue here. I modified phone settings several times and try with another apps but nothing working so far
I MAY HAVE FINALLY FIGURED OUT A POSSIBLE SOLUTION!
Disable "Dual 4G" option in the settings.
No issue so far for 3 days now
