Will my phone work here?

Compare the bands above with the bands your phone supports. If your phone lacks a band an operator uses, you may get no signal — or no 5G — on that network. Also check whether your phone supports eSIM on the Devices page, and dial *#06# to see whether an EID (eSIM identifier) is shown.
