TextNow APN settings not staying

[Jr Stewart]

I have a Motorola G play 2021 carrier unlocked. The APN that shows is T-Mobile US ( greyed out) and (T-Mobile US MMS greyed out ) I've got TextNow Sims and trying to set it up the APN like they said but the MNC won't change From 240 to 260

Welcome to Android Central! Did you have to create your own APN settings for TextNow, or did they automatically show up?

Welcome to AC!
Once you put a new sim it should automatically populate a APN?
