How do I use the zip coverage checker to see if I am on Sprint or Tmobile?
You’re not yet a customer and trying to figure out which SIM you’ll get? If you use the coverage checker and then from there hit the “Shop Phones” button you’ll see all the phones sold by Republic on the next page… If they all show normally, you’re likely to get a GSM configured phone when ordering from Republic. If phones like the LG K30 or Samsung J3 are showing as Not Optimized for your area, then you’ll get a CDMA configured phone.
I’m not sure what you’re asking, so just to cover the rest of the bases… if you’re wanting to know what coverage a current phone has, please see:
