Is this a dual SIM phone?  Is the bands compatible?  I recall the North American version was only single SIM.

I'm using Asian version that's why i have two SIM card signal.

Hey @cbrandonisio, I hope flashing the custom rom has helped.  Good luck!

@cbrandonisio Based on https://willmyphonework.net the China variant is missing PM's best LTE band. Try locking your phone to 3G, or set LTE OFF. Don't know how that's done in Android.

I have the international version of the phone, the problem was fixed by flashing an updated/custom device baseband and firmware.

PROBLEM RESOLVED: Flashing the newest available oxygenOS baseband and firmware, in conjuction with sultanXDA's lineage os 14.1 ROM has solved the problem. Phone is set to LTE/UMTS (PRL).
