Hi,
I have Lenovo A820e which is CDMA + GSM phone.
I am unable to switch on data either on CDMA or on GSM. However, the phone is able to use wifi.
I have saved the new APNs for Relaince CDMA and Idea GSM. But to me, it seems that China Telecom is preventing data connection other than its own.
How can I solve this problem ?
Plz. help.
A820e
Hi, I have also an A820e. Got to the same point. I've installed a ROM with GApps and got everything working except I can't get 3G data, only GPRS.
I think it's ROM related.
Have you been able to find a solution?
It seems that Lenovo A820e doesn't have the 2100 band which is required for 3G communication in Europe.
The way I was able to activate data in the ROM that has the google services is by introducing the following code in the dialer:
*#*#4763#*#*
After this a message telling me that the data has been started appeared and I was able to control.
Also before this I made a change in system/build.prop
to default the network to gsm. I've added:
ro.telephony.default_network=1
(Should be rooted to have access to this. I've used Root Browser)
Hope this helps.

*#*#4763#*#* - did not work for me... It seems it depends on ROM

Which ROM are you using ? Can you give me the link ?

I have got one solution from somewhere is that we need to downgrade back to 4.1.2. But for that you need to download file from:
http://sbf.droid-developers.org/phone.php?device=8
Then You need to extract the original system.img from the archive as well as logo.img in case the phone doesn't allow you to flash system.img, you can use logo.img to kick the phone out of Fastboot. You will need to install Motorola ADB drivers on your computer in advance, and also need a fastboot.exe file which I think you can find via Google, but if you have ever rooted your phone in the past, usually that also came with fastboot.
Anyway, get into fastboot mode by turning off the phone, then holding down all 3 buttons. Use vol- to select Fastboot and vol+ to choose it. Phone should boot into fastboot.
Connect to PC and issue command:
fastboot flash system system.img
If it works, the phone should be downgraded. If it says flash failed, then downgrade isn't possible. In that case, if the phone is stuck in fastboot mode and can't be rebooted, issue this command to get out of fastboot.
fastboot flash logo logo.img
That should let it reboot as normal.
I actually doubt it's possible to downgrade, but I haven't tried it myself so I can't say for sure.
there is a workaround for this, but it requires unlocked bootloader and possibly a ruim flashing tool.
i'm not sure it it will work for any of you, but at least i managed to make my ruim work in ukraine.

I am totally struck after 4.4.2 update. My Droid Razr M was so fine, now almost useless. No data on CDMA. I am from India and using Reliance. Battery drain is so fast, cannot even surviving one day, earlier it was almost with juice for 2 days. Waiting seriously for some work around.

There is a new type of micro sim cards available at Reliance Web World. By changing to new UIM card at reliance, CDMA data will work in Kitkat.
I am using CDMA/ GSM Sim unlocked mobile.. If I change the Sim will data work after updating kitkat.. Coz it was not working with the same Sim.. Have you checked it by using new Sim after kitkat update?

Yes CDMA data was working before update to Kitkat..but after update No data on Reliance CDMA network. Test messages & voice calls are working.
Micro SIM are not available in Reliance Web World they will ask you to cut the SIM for using it.

Then it will definitely work if you purchase the new micro SIM and activate to your number. Here its available in reliance web world. There is another option to start CDMA data is that u have to restore back to JellyBean.
I have purchased New Micro SIM but still Data is not working. Downgraded to Jelly Bean and used normal SIM, now Data is working fine.

You have to activate new SIM using any ZTE mobile. Then Data will work fine. I have done it and its working fine in kitkat.

I activated my micro Sim using Samsung young CDMA mobile...but it was not working after updating kitkat. You have to activate it using *228 enabled imported CDMA mobile.. Your ZTE mobile is purchased from reliance or it is imported mobile phone?

call me at 9371266944.
From the photo of the RGER series SIM that you have shown, it seems you cannot cut that to nano form factor. I can see that this is the old type of SIM card where the circuit section is elongated.
In comparison the RECRU series has a SIM which can be cut to nano size without cutting off parts of the circuit.
So from what you said, users who need data on a phone which accepts only nano SIM cards (e.g. Droid Ultra/Maxx/ Turbo), will never be able to use data.
That is simply not true.

Here is a guide how to enable VOLTE in RR without Jio4gvoice app.
Supported ROM :
RR 5.7.4
Instructions
1. Open ES File manager and enable hidden folder. Search .Jio4gvoive folder delete it. Then delete jio4g app and voice app.
2. Now again install jio4g voice app and register through it.
3. Now Delete Jio4gvoice app.
4. Open dialer and dial *#*#4636#*#* .
5. Scroll to end and open OEM specific settings.
6. And turn on MBN AUTO LOAD, volte debug, VT DEBUG, WFC DEBUG. ( After clicking on it will show turn off so don't get confused with it. )
7. In SIM Settings Disable Connected line indetification & open APN settings.
8. And If you have loop APN just edit APN "www" to "jionet" and save it. Keep APN PROTOCOL AND ROAMING PROTOCOL TO "IPv4" otherwise internet will not work.
9. Now reboot to recovery and wipe dalvik cache and cache only.
10. Restart your device and open dialer.
Workaround :
If you are not getting network in jio then open system ui tuner by pressing on settings icon in Qs panel or search it in setting.
Then add tiles "LTE" . Now enable LTE from QS Panel(check screenshot) You will get network.
If you are getting volte icon like volte1 and volte2 then volte is enable. Just try to call and enjoy. If it's help just click thanks.
If anyone is on lineage os try this and report me back if it's working on it too then I will edit it to lineage os too.
Those who will publish this guide in their site please give proper credits.

Thnx.. alot.. worked for me..in one go...:good:
Not this one but simple trick worked for me given by @TechGeekD without first step
no need to download any application to fix VoLTE
1). clean install latest build
2). goto settings -> SIM cards
3). set cellular data to Jio 4g & Calls to Jio
4). goto SIM 1 settings (or SIM 2 settings if Jio is in sim slot 2 )
5). see if Enhanced 4G LTE Mode is enabled or not !! enable it if not
6). goto Access Point Names (aka APN)
7). select 3 dot menu press Reset to default
8). add new APN with settings given below
APN SETTINGS
Name: ims
APN: IMS
APN Type : IMS
(notice one thing APN Type & APN is written in Capital !!!)
do not restart thats the bug ims setting stays there but not visible in settings cause after restarting we can not add new ims setting with same APN and APN Type but simple tweaking with APN & APN Type will fix it (but still don't restart after VoLTE gets working it will be gone again and you can't tweak it now)
Edit :- Selinux needs tobe on permissive mode

This is a permanent fix. His method is temporary due to restart won't allow volte. But this method works charming after restart also. Your choice, I am not forcing...
Not working here. I am on R 5.7.4. Had done a clean flash.
Tried every method. And even if VoLTE works, neither you can send sms nor receive.

That's why moved on to stock until codeworkx will remove VoLTE fix from the to do list. And i yes i have a lot a patience. So i can wait. As developers has their personal life. And they have to manage it.

Did you tried these workaround? Can you get volte icon in dialer in front of sim1 and sim2? If you are able to call through jio4g voice app. Follow steps from starting like deleting .jio4g voice folder and all that. These were tested personally by me in RR . If nothing works I better recommend you to flash 19s eui then clean flash lineage latest rom ( for bugs report to rom's threads) don't try to flash any other bootloader or modem files. As @codeworkx also mentioned that lineage is nothing to do with bootloader or modem. Note - MM have issues but nougat don't.

Try other JIO sim from a VoLTE supported phone.
OR
Put your JIO sim in other phone which have VoLTE working then put it back to your phone, try both method because this helped me sometimes.
You can now use your Jio 4G voice app on your Treble ROM on any device with VoLTE not working by following this guide.
1) Open settings app.
2) Go to "Network & Mobile" --> "Mobile Networks" --> under the "Advanced" --> "Access Point Names". If not found open the APN settings located in your settings app by searching for it.
3)Create a new APN with the following settings :
Name : ims
APN : ims
Type : ims
Protocol : ipv4/v6
4) Now save this APN.
Note: The APN may not appear in the APN list. But, do not worry.
5) Now, install the Jio 4g voice app. If you have already installed and used the app, follow the steps below (6,7) . Else, neglect them and Go straight to the App.
6) Clear the Jio 4G voice app Data and Cache.
7) Delete the hidden ".Jio4GVoice" and "Jio4GVoiceFiles" using Root Browser or any file explorer app.
8) Open the Jio 4G Voice app and grant all permission and also enable the Rich calling feature so that your call goes through the Jio 4G voice app even when dialed through the default Dialer App.
That's it! you now have 4g calls on your Treble supported ROM!

Thanks a lot buddy, I am using Lenovo Vibe Shot' z90a40.
Using a custom rom- Mokee - Android 7.1.2
Recently, I installed a Jio 4G sim and activated it. But I was able to use only network services until 8 read this thread, from where my jio 4G voice call is now active ( before it was only inactive).
Now I'm able to make calls using this app all the time.
Thank you.
I periodically change the firmware. And recently I have installed Lineage 14.1. Everything worked well, except for one thing: in the description it was written that mobile data only works on the SIM2, so I moved my SIM card to the second slot, but the mobile data still did not work. I checked: the connection is available - you can call, the Data roaming is switched on, the access point is selected - the Internet still does not work. Later I installed Ressurection Remix 5.8.5 - and with it the same problem. However, on all other ROMs - Cyanogen 13, Motion Rom - the Internet on both SIM slots works (it's not a hardware problem). Please, tell me, what could be the problem and how to solve it?
