Internet Connectivity lost, can't be returned ! - Galaxy S II Q&A, Help & Troubleshooting

I have recently lost my data connectivity while toggling Use packet data. Since then I have tried resetting the APN, restarting the phone, disabling SIM lock, even a factory reset, but still no trace of the"E" sign, this is also the case with other SIM cards. How can I ever fix this ?

No 3G/Data!

I enabled Data and disabled "2G Only"
But it doesn't use any data!
I paid for a one month...
Help?
Are there any Access Point Names? If your data connection doesn't know where to access the network, it won't.
How can I make one??
Doesn't 3G or Data connection should be automatic??
Go to Settings > Wireless > Mobile Network > Access Point Names
Then menu button, and Reset to default !
Make sure Data Enabled is checked in Mobile Network settings
If reset-to-default fails:
Go to the site of your carrier, they will have instructions to automatically set your phone, and if they don't support your phone, they will tell you how you can set it manually.
Unfortunately nothing works!
I think that phone itself doesn't have 3G!
Or maybe MiniCM....
Because I inserted my SIM into another phone (GS2) and the Data worked without any problems and automatically!
Weird... it's working now!
Maybe after using it in another phones did something?
My guess is: you turned your phone off to get the sim out and turned it back on with your sim inserted again AND data connection on... it probably searched for networks at the sim-initialization during boot. If you had left data connection off it probably still wouldn't have worked lesson learned i suppose. good luck

WIFI Problem, restore the backup of another SIII

Hi.
I have two s3 phones. I tried to create a backup using one S3 and restore it on another one (too have same apps on both). Everything is fine, except WIFI connection fails on second phone.
I tried to clear dalvik-cache, but didn't work.
WIFI connection and WIFI-Direct don't work. WIFI sees the router, but cannot connect to it. It shows zero signal strength.
I did the factory reset on second phone and wifi worked.
It seems that some settings/data should be cleared to make wifi work again.
Any suggestion?

unable to use 3g data

My droid razr suddenly unable to use 3G.
It stuck on EDGE only even i change it to 3G.
I have changed APN manually, change setting manually by using *#*#4636#*#*, change ROM from CM13.1 to CM14, it didnt work.
I tried several apps to know is that my phone hardware problem or software.
Then i found my phone still able to read 3G signal, but unable to register.
While i force it to 3G, the signal is full but while trying to use 3G, signal lost and back to 2G without any problem.
Im sure it is not about my SIM because i tried many times on various SIM and the problem still persist.
Please help me to fix it manually even the step is as hard as to changing MAC address manually.
Thanks.

Network access denied, Huawei Y6 Prime

Hello,
I can connect to all the Wifi but home Wifi which stubbornly rebuffs me with 'Network access denied'. The issue happened after I came back from a trip to france then China and tried to connect. I live in HK and the network (that had not changed) could be detected, but connection impossible. All other Wifis are fine... and this happening 2 weeks after I bought this phone..
I tried to reboot restart the phone, forget the network and reconnect to it, changing SSID of the phone, changing IP address. The phone won't connect.
When I go in 'Setting, Backup and restore', I find no possibility to reset all the networks, contrary to the possibility that seems to exist on other Huaweis>> Is this normal or this could be linked to a phone issue ?
So basically I am totally stuck after trying in total 2 hours of everything I found on the Internet.
If the last option is to totally reboot the phone to its infancy factory state, I am afraid it will be more painful to reinstall everything rather than having no Wifi.
Do you have an idea of something else I could try ? Thanks for your help

Question Wifi can no longer be enabled.

Just put a new Sim card in my phone (switched carriers) and now my WiFi refuses to turn on. I have tried to reset the network settings, switch back to the old Sim, and even factory reset my phone. When I go into my settings and look at my phone's status, I have no WiFi MAC address, it just shows "Not Available". I'm pretty sure it broke, but I want to see if I can fix it somehow software wise before I go and buy replacement parts.
E1: BT still works, so it is not the modem.
E2: Removing Root has not worked either.
E3: Can't force on with ADB.
