Will a LightPhone work with RW?
I’m afraid the answer is no. Republic’s unique (sufficiently unique to be patented) blended WiFi/cell service requires one of the carrier agnostic factory unlocked phones listed here: Republic Wireless Phones – Republic Help. You’ll want to be certain the phone you wish to bring is an exact model number (and in some cases build number match) for those listed.
This Republic Help Center document walks you through the entire process of bringing a phone sourced elsewhere to Republic: How to Bring Your Own Phone to Republic Wireless (BYOP) – Republic Help.
Even better is this contribution from a fellow member (Republic likes to call customers members) linked here: How to Find a Compatible Unlocked Phone.
Can you tell us what sparks your interest in a Light Phone?
My mother is quite elderly and needs a very simple phone to use.
For what it’s worth, Samsung phones offer an “Easy Mode” that simplifies the home screen layout. There are also apps in Google’s Play store that do the same. Either way, the underlying reality is your mother would still be using an Android smartphone but in case it helps.
Thank you for that helpful information!
