I turned my phone off before boarding a plane, and then when i turned it back on it had lost all the data connection info. Now it doesnt see the phone network either. I am using an unlocked phone on t-mobile in the US...It has worked fine for the last 6 months....
I tried re-entering the data connection info, but i still down get either a connection to tmobile gsm or edge or gprs. When i go to manually select networks, it only sees att, which of course i cant connect to, cause of my sim card being tmobile.
Any thoughts ?
TIA

Is it possible that the phobe can lose the unlock ? Would only seeing ATT be the a symptom if this were the case ?
TIA

My galaxy s will not have a data connection. its unlocked and the network lock is off and i still cant get a data connection. the phone recognizes my sim card and everything but still no data connection. I have a att sim card by the way.
Hi
I am in Kolkata India and recently switched from a 2G to a 3G plan with Vodafone Kolkata. Ever since then, my problem is that I am unable to connect to 3G using WCDMA. Neither voice nor data works. If I revert to GSM only, then voice and 2G works fine. Wifi has been fine and my saviour at home.
Phone details: Sony Xperia SP C5302 running Android 4.3 build 12.1.A.1.205.
I have confirmed with network service that it is not a SIM card issue, by carrying out the foll. tests already
1- Signal strength in the area of use : At the time when I am unable to connect to 3G, my colleague sitting in the next desk and using a Motorola phone is consistently able to connect to the same 3G network from his phone. So the network strength must be fine.
2- SIM damaged or dirty - I have obtained a new SIM card as replacement, after this problem started, from my service provider yesterday. But the problem is not resolved.
3- Manual network search and connection - I have tried this many times, using WCDMA only or WCDMA(Preferred) options. In either case, only on rare occasions, the phone was able to connect to a network. However, 3G data connection (H+ icon) did not show and then the phone disconnects from network. On most occasions, when I manually attempt to connect to the 3G network, I get the message "Could not register to the selected network. Make sure SIM is inserted."
3- Trying different SIM/Handset - I have tried out both options of switching SIM and handset.
- My SIM on Motorola handset - connects to H+
- Another SIM on my Sony - momentarily connects, then disconnects and then does not connect to network.
Please let me know if anyone has faced similar issues and found any resolution. Thank you in advance.

I think that there's an option to use 2G instead of 3G in the settings menu, have you checked to see if that is enabled?

That is the WCDMA option I've mentioned about, there was no other setting for this.
Anyways, it turned out to be a hardware problem. Got the "mother-board" replaced for free as it was under warranty & now working fine!

Good to see that you've sorted out the problem!
I have a moto X 1st gen here in India. Its unlocked,not rooted. One fine day it thrower me an error "your sim card does not allow a connection to a network". And I am without network in my mobile.
My IMEI is same as in the battery
Device is not rooted
Sim card works fine in other mobiles
Tried different sim cards but still same problem
Didn't fiddled with any network settings.
After reading through XDA threads I did
Cleared data/cache
Restored the stock firmware again.
Did that network menu reset to switch radio on and off many times
Not able to get any network signal at all. Is there anything I am missing?

Hey all
Question for those with dual sim exynos version running pie.
Can you successfully wifi tether on both sims.
Currently I can tether the mac successfully with sim 1. However sim 2 I just get a no internet screen in all browsers. If I browse on the phone from data on sim 2 I get full speed 4g.
Sim1 has poor signal where I'm working hence switching to sim 2. Tried wifi and bluetooth tether and get zilch on sim 2. Tried wipe cache and on mac forget network changed tether wifi name as well and still the same.
Be handy if someone who has 2 sims can try switching to secondary sim and wifi tether and let me know if all is well.
