Intermittent service after unlocking by IMEI



Hello there, this is my first post here, I searched all the forum but could not find any solution to this.

I have a Optimus G E987. Unrooted, unflashed, with original rom, didn't do anything to the phone yet as I recently got it from a friend.

My friend was under a different carrier that I am. Since his contract had expired I was free to contact his carrier and get the unlock code to unlock my phone by IMEI. After succesfully unlocking the phone, I inserted my old sim card, it was a Standard Sim so I had to trim it to fit on the Micro Sim slot the Optimus G has.

Everything worked beautifully until I started having signal issues, both data and phone.
It does not happen everywhere, but it definetly happens at places I had perfect signal with my old device like my work place. To solve it, most times I can go to the network settings of the phone and choose the auto select option. This restores the service but I lose it again in a few minutes. Sometimes this does not fix a thing and I can not recover service at all.

I know its not a hardware issue as my friend had no signal problems whatsoever. Maybe I need to set up something in my phone to get it to work properly but I am completely clueless. I suspect it may be the sim card as well.

Any help will be greatly appreciated.
