[Q] Nokia Lumia 1520 no internet access

Hi all
I'm new on WP
I had changed my SIM card but I can't connect to SIM data connection
I could connect to internet before, both SIM and WiFi, but now no internet access
I had reseted my phone and it's worse now
Now I can't connect with WiFi or SIM data
I asked my carrier, No problem on SIM card
What should I do?
------------------------------
WiFi problem solved but still can't connect to SIM data
You may need to do a hard reset on the phone, if you can't connect to WiFi even. That shouldn't have anything to do with the SIM.
If it was *just* the cellular data, I'd say it's probably an issue with the APN. But WiFi can be used without a cellular connection at all; it should never *not* work.

I tried with keeping off and on mode for data usage. though its not at all detecting network signal for both sim card when I go for roaming.
I tried restarting , reinserting sim card everything. but when I reach to home network its works perfect.
Why am losing signal?

No brother, its not at all about data connection, its about network signal. I kept this thing with both data service on and off mode, but the thing is about network signal. It am not even able to call as I dont have signal those time.
Than it is something related to your provider.Some kind of restriction in roaming , or your firmware do not support frequencies in places where you travel
