Samsung Note 2 SPH-L900


I’m Victor from Mexico (sorry for my translated English), I have the Samsung Note 2 SPH-L900 recently installed MK60.1-l900-170418-HISTORY and I do not get calls… If I have signal, I make calls, data in H+, sent and received sms.

I appreciate any help like resolving to receive calls.

Can not answer the phone?
