PrePaidGSM.net Forum (Archived) - TuYo Mobile not activating SIM cards anymore.

For those who use TuYo Mobile, I thought you should be aware of this. While looking on eBay I saw some TuYo SIM cards for sale and the seller was saying that TuYo does not activate them any more but you can on T-Mobile.

I called TuYo and the CS rep whom I talked to said that they had not been activating SIM cards since April 2010.

He said that they might in the future, but I am not sure that is to be believed.

However, I do have a handful of TuYo SIMs and more than a handful of T-Mobile activation cards, and yes they do work.
and if you have phones locked to TuYo they will work this way.
