Was very happy with this for the 2 months it worked.

 

Tested it recently by calling the number from another line and it goes to a fast busy indicating out of order line.

 

CS isn't even trying to fix - just ask "What is your phone model" and then the 40 or 60% compatible which previously caused them to say "It will work" (and it did) now say "It will not work".

 

T-Mobile upgraded lines to 5G and Ultra isn't trying to make older phones compatible - instead trying to sell new phones.

 

Too bad.

It gave me a US SIM/phone # and it accepts promo SMS (short codes).

 

I guess I have the option of trying to find a compatible local burner phone with which it will work - if such exists.

Could insist on testing Ultra SIM before purchase.

 

Does anyone have a suggestion for a phone for this purpose?

 

 

old post... but came up in my search... and can atest that Ulra Mobile PayGo works fine.
