I had to call the customer service representative and they requested I get a new 5G sim card and do a sim swap.

If not for the fact that my old sim card which is also a nano sim didn’t support the 5G network, I wouldn’t have swap the sim with a new 5G sim card.

Cellular network service is one of the major reason one would say this sim card is too old for this new phone. Maybe you have a 3G sim card in 2021 and plan on using it on your new 5G smartphone.

Honestly I will loudly say the sim card is too old for the phone.

Second is the sim card size and the new phone sim slot.
