What phone?   Most prepaid androids have no bands other than 2g for outside the USA.

The S6 edge is not a cheap prepaid phone.  

You need to contact the new carrier for help.  It may not have compatible bands for LTE and may need to be programmed for their network.

No.  But I’m surprised as most overseas carriers are GSM based, not CDMA.
