because on my phone I can select the carrier I want at all time ,
Is their a way to input , like we can input band to use , Ok , just use This carrier ?
thas is why I give you those line that come with the AT command.
AT+QNWINFO = +QNWINFO: “FDD LTE”,“302720”,“LTE BAND 5”,2426
AT+COPS? = +COPS: 0,0,“Rogers Wireless”,7
maybe we can program something that only look for that.
and that is the band they use , If i can filter anything else , that could be a good start.
My carrier bands are
UMTS
B2 (1900 PCS) UMTS
B5 (850) UMTS
And
LTE
B4 (1700/2100 AWS 1) LTE
B7 (2600) LTE
B17 (700 bc) LTE
