4G connectivity issues

[Shaygol]

Hi all, I searched for this issue in a few forums but didn't find it anywhere, so I'm posting it here in the hope that someone might help me.

I live in Israel, my lg g3 d855 was bought in Switzerland. My carrier is Golan telecom.

As soon as I inserted the Sim card and turned on the device I immediately got APN configuration for my phone, including 4G.

The problem is, that when choosing network mode: LTE/ WCDMA / EDGE, the phone has 4g connection for a while, but as soon as this connection is down (for instance, when connecting to Wi-Fi), it won't reconnect again, not to 4g or 3g or anything. I can still get calls in and out, but no data.

Resetting the device and/or turning mobile data on and off won't solve the problem. Only changing network mode from LTE mode to wcdma or EDGE and then back will get the 4g connection up again.

My current solution is to work in wcdma/edge mode. In this mode i don't encounter any issues. However, it's a Shame that I can't utilize 4g capability.

I wonder if it's a hardware issue, which doesn't seem probable, or a software issue that is caused maybe by the fact that my ROM is European. I have original stock ROM and no root. Do you think that changing the ROM might help here?

Thanks for your attention.

No-one has any idea?

Welcome to the forum, at least.

Looks like we're stumped so far. Have you considered trying a different SIM?

Sorry, I'm just not hip on other countries. I'd take it to my carrier and ask them if there's something missing in the APN settings.

I thought to try that also, i will. Do you think overwriting the European ROM with an Israeli one might help?
