iPhone 6S+ shows "No Service" often

Hi I know this is a little bit late, but I experience the same issue. My phone is locked to a carrier Smart, but when I put on my simcard it says no service but sometime I usually get 2-3 signal reception. I know I am in coverage area of smart where cell reception is strong but nonetheless I got only 1-2 signal. Does somebody experience the same issue? Please let me know if you had fixed it already.

 

what model are you pertaining

 

I am using Ip6s. In the settings, there is "No Service" but my carrier is Smart 36.1 and I am currently on ios 12.4

have you tried this?

by December it will more than 4 years old. why not dispose of the iPhone 6s Plus and get something that actually works?

Sayang din ang oras kaka-ayos

 

Hi. Yes I've tried possible solutions I found at random sites pero di paren talaga eh. Naipacheck ko na sa technician, and then found out na fake pala yung nailagay 'daw' na antenna sa phone ko. Valid naman IMEI nya and legit siya na iPhone pero ewan eh

 

A used iPhone from a tsange?

 

try calling 112, if does not work then the problem is with the baseband
