Hi @DelphiPax,
Sorry to read that you are in a difficult situation. You might want to look at this review of Tello recently written by @herbie, as well as the older review by Roland, as it seems to be a good choice.
You originally wrote that you “trashed” your Google Pixel 4a. In doing so, was the SIM card damaged or lost? If so, you will not be able to keep your My Choice plan, because Republic Wireless is no longer able to activate SIM cards on the My Choice plan.
If the SIM card is still functioning it can be moved into another unlocked Pixel 4a, or any unlocked phone on this list: https://help.republicwireless.com/hc/en-us/articles/115005789107-Republic-Wireless-Legacy-Phones
It can be hard to find a compatible phone, so if you see something online that you think you’d want to buy, please let us check first to make sure it looks like it would be compatible.
