Hi,
Sounds to me like your just in poor service coverage areas and losing signal. Might not be much you can do about that really. But you can ask about it in this dedicated help thread in your device section,

Good luck!

Hello,
I have the Samsung galaxy S3 compatible with the 4G (model is i9305) network. I am in an area (Switzerland) covered by the 4G. But it seems that the phone is always connected to the 3G. No 4G icon on the notification bar.
Have you an idea of the problem ?
Thanks for your help.
You'd need to make sure you have Correct Access Point Names (APN) set for the carrier you have. Also need to turn on LTE through settings.
Please post in [HELP THREAD] Galaxy S3 Ask any question. so that one of the experts may be of help.
My network mode is set as LTE on my nexus 5, but when I do that my phone won't register into my network provider. I am sure that I have enabled LTE through my network provider. But when I search for network providers manually it shows my provider but I'm unable to register onto it.
My question is, does it mean that my phone supports the LTE band of the network providers that I got in my search result?

SAMSUNG S4 VERIZON
MODEL NUMBER: SCH-I545
BUILD NUMBER: LRX22C.I545VRUGOC1
ANDROID VERSION: 5.0.1
I recently moved to Nicaragua, Central America, and I am trying to use a local GSM carrier (Frequency at 850 - 1900 Mhz). After inserting the SIM card, the phone does not recognize the carrier (FYI, carriers name is MOVISTAR). Phone specifications are mentions above.
The phone screen brings up a message "SIM CARD IS NOT VERIZON". The only time that the phone is able to recognize the carrier and get some signal, is when it boots up. Afterwards, it just closes out with no signal bars and the message pops out on the screen.
Could you please help?

Hello, and thank you for using XDA Assist!
The 920i is the international model, and thus misses Band 4 (1700mHz) which is used by the USA GSM operators (AT&T, T-Mo, MetroPCS, et cetera). This means you won't get 4G LTE with this device.
Also, if trying with T-Mobile, they alos use 1700mHz for HSPA (3G), a frequency your device does not have either. So unless T-Mo still supports 2G (I remember a planned phasing of that out at some point), your device will not work with their network.
AT&T on the other hand, uses 3G 850/1900 frequencies, so you should be okay.
At any rate, I could be optimistically wrong. So, please create an account, so you cna post in other forums, then either post in the above linked thread, or in the S6 general help thread:

Hope this helps, and good luck!
