Can I install a SIM from a Galaxy s6 into an S21G Uncategorized June 1, 2021 Forums AndroidCentralLeave a Comment on Can I install a SIM from a Galaxy s6 into an S21G I just upgraded phones. I want to stay with the same provider/plan. Can I simply remove the SIM card from the S6 and install it in the S21G? Or is this an issue that will require support from my provider? Sharing is caring!
