Hello,
I am experiencing a very weird issue with my 3G mobile in the last 2 days. Suddenly the mobile data network is not working anymore and I didn't do anything that could be the cause of the issue.
What happen is that, if I enable the 3G mobile data, the phone tries to connect and it succeeds for 2-3 seconds (in fact the H+ symbol appears) but it immediately disconnects: this continues forever, connecting and immediately (2-3 seconds) disconnecting again.
I am using CM 11 with and mobile data used to work perfectly before 2 days. I also tried to wipe all data and reinstalling the ROM but nothing, I also updated the modem but nothing again. Attached there is the logcat taken from the moment of the connection to the moment it gets disconnected.
I don't understand if the issue is related to the phone itself or to the mobile company (I am using DU in Dubai).
Thank you very much.

It doesnt look like it is a phone fault (i read logcat). Many error caused by lost connection/null/unspecificaited. I saw that apn called hipri (sth like that) did quite well. I saw that phone was trying to use roaming but it failed too.
My advices
-Check APN on your provider's website (if it doesnt work try next ideas)
-factory reset your phone
-Reinstall CyanogenMod
-Install Stock 4.1.2
-Check your sim card in other devices
-Check other simcards (with the same provider and other as well) in your device
-Go to your providers costomer services , tell about your problems and researches u did.

i dont know if some of you have experience this.
Just recently upgraded my htc flyer (32gb wifi/3g) fromm gb to hc, it was working fine for two days till one day an error occurs and restart my device, after that, mobile network is no longer working, i cant click the option as it has turn to gray, w/c in unclickable. Sometimes it displays mobile network is turned off. Ive already reset it and reinstall HC, after resetting, it can detect my mobile network, but after 5 seconds its not working anymore and displays no service.
I have posted this on the Sony Xperia P forums but I have yet to to get a response. As this is a pressing issue, I have to return the phone to the store by tomorrow at the latest or not at all, I post it here aswell.
I just bought my Xperia P last week. Since I've been having connection issues. It started, as far as I can tell in such a short period of use with the wifi connection. When I would go out of range of my home wifi it would freeze, only fix was to reboot the phone. It would not switch over to mobile data at that point either so I had no connection at all untill I rebooted. I've since been trying to figure out why the wifi froze. I've reinstalled the latest phone update through PC Companion and I've factory resetted the phone on the device itself.
My wifi issues appear to be fixed after this however, and equally annoying, now my mobile data won't work. I see the H appearing next to the reception bars and arrows up and down appear next to it but no web page will load, facebook or mail don't work either. I've been trying going in airplane mode, just toggeling the data connection, rebooting the device, nothing works consistently. Sometimes mobile data will work, but more often it wil not.
I have contacted the store and they are willing to exchange the phone. However, I wanted to check here first to see if this is a common problem, if its a software issue, a new phone won't help much. If it is a software issue, is there anything I can do to fix it myself?
The phone came with ICS preinstalled.
Hello,
I bought the P9000 US Edition recently, which runs the Elephone_P9000_M_20161107 ROM. After getting it, I didn't even start it up but immediately updated to the latest LinageOS with Android 6, but the SIM card wasn't detected then.
I flashed the latest official ROM 20170110, not realizing this isn't meant for the US Edition before seeing that the IMEI number was wiped, causing the SIM card not being recognized. Thankfully, I have a full backup of the original state at hand, so I could restore nvram easily and the mobile connection started working.
However, after that was solved, I encountered problems with the mobile connection:
Searching networks sometimes takes a long time, resulting in no connection at all in the meantime.
When I'm connected to 3G networks, it shows that it has a data connection (small 3G logo on the signal indicator), but I can neither make or receive calls, send SMS or use the data connection as long as it doesn't switch to 2G or 4G
The data connection problem sometime manifests with 2G and 4G, too: the small logo shows but no data comes through.
"Phone idle" is by far the largest battery consumer in the battery stats (not even the screen outweighs it at any time)
I just found out by trying that enabling and disabling airplane mode sometimes solves the problem, maybe because it results in a reset of the modem. I contacted Elephone support and they said that I had to reflash the original stock ROM for the US edition and if this didn't help, I had to send it in for repair, because flashing a wrong ROM corrupted the modem data.
After that didn't work, I even reflashed my backup, selecting each and every partition (except for the last two partition, flashinfo and sgpt[/] or something like that, for which I didn't take a backup). This seemed to alleviate the problem a bit, but not completely.
TL;DR: When the phone has a 3G connection, neither calls, SMS nor data work. Sometimes this also happens in 2G or 4G. Support says I corrupted modem data when flashing a non-US version ROM. I restored a full backup of the original state but it didn't change much.
Any suggestions on how I could solve the problem?
Are you in the USA?
I'm in Canada and using the EU version of the phone.
A solution I have found is to change the bands. This can be done by:
1) Press on the dial pad *#*#4636#*#* this will enable engineering settings.
2) In the top right press the '3 dots'
3) Press 'phone information'
4) Press 'select radio band'
5) Then choose a band based on your location or play with them see which works best exit and try that.
6) Redo the steps to change again should you need to. I typically play around with the bands to find the one that works best.
7) If this doesn't work maybe check your network APN settings? Mine are automatically filled for Bell and Rogers in Canada. When I travel in the EU it generally auto-fills as well using the network 3.
An error that occurs when I attempt to enter the 'select radio band' under 'phone information' is the error code "com.android.phone has stopped" with the toggle for 'Open App Again'. A solution I found to that problem is to soft reset the phone.
Another error I frequently encounter is "Process com.android.phone isn't responding"
Not really practical given the average user wants a device that "just works".
First of all I know it's a crap phone.
It is not my wifi that is the problem, it happens on all wifi networks.
I didn't drop the phone or anything like that.
I am running stock Android 6.0 (no root)
I previously used a hack from this website that involved putting code through MinimalADB to mount an sd card as the main storage as this phone doesn't support apps on sd card (Did after that hack!).
On my phone randomly when I am using my wifi the wifi stops working randomly. There is no warning and no sign except only the left arrow beside the wifi bars lights up (the bars are still full). Nothing at all will load. The only solution I have found to this problem is restarting my phone. As this happens usually after 10/15 minutes of using the phone it is beyond irritating. The Bluetooth also goes and even though it says I am still connected to my headphones no sound will transmit. Mobile data still works.
If anyone can help it will be super helpful.
I have problem with my p20 lite using mobile data even when I have it disabled. I have prepaid sim card and I even called my provider and thay can't find any issues on their side. I have tried putting other sim card and I have the same problem, and my sim card in other phone is OK so I think I have eliminated that it could my providers fault. So I have disabled everything wifi, GPS, mobile data, background data EVERYTHING, and still every few minutes it takes 0.03€ of my credit. I even did factory reset, everything is stock, phone was not rooted and still problem persists.
any suggestions, thanks
This happened to me once
When I changed carriers took 40 minutes for signal to come back
Try leaving it in airplane mode for 30 minutes then turn it off and leave it on just wifi see if that works
