My iPhone 5s wont get any 2G signal inside the house which shows no service. But my Mother’s iPhone 5s which has same carrier gets full bar of 2G signal. While outside house my phone gets one bar of 2G signal. My Mother’s phone gets full signal. My phone works fine with 4G. Only 2G wont work. I already did network reset and did factory reset from ipsw file, still the problem remains. The IMEI and Modem Firmware are also displayed properly. Sorry for my bad english.
I don’t know if they have 2g anymore. They Still have 3g and 4g and some places have 5g. Some phones might not work and it might might be the ios version.
