Compré la tarjeta porque muchas compañías no querían activar mi celular chino, un Xiaomi Note 12 Pro+ 5g, y cuando lo puse dentro de mi celular pude llamar perfectamente al servicio de activación donde me pusieron mil excusas sobre que mi celular chino no funcionaba y no iba a funcionar y me desactivaron mi tarjeta SIM de Amazon, fui físicamente a una sucursal y me atendieron mucho mejor y me activaron una SIM literalmente igual a ésta, y ahora estoy con internet perfectamente funcional con un plan prepago como la de esta tarjeta. Bien producto, terrible servicio al cliente.

Works as prepaid sims for T mobile

I had postpaid T mobile connection (part of family plan) and I wanted to shift to the prepaid one (T mobile connect 15$/mo) as it was cheaper for me. I called up T mobile customer care, they asked for the (1) family plan account #, and (2) the account pin (3) a new sim card (this one from amazon) I just had the account # and told them the name and cell no. of the family plan head, so they called him up and got authorization to drop me from the family plan. They then transferred me to their prepaid division, they asked me for the Sim # (not the cell phone no.) that is written on the back of the sim cards purchased from amazon. Then they just transferred/ported my old no. from postpaid (family-plan) to my individual pre-paid plan. After, the phone got disconnected with customer care (as the old sim now became defunct). I replaced my old sim with my new sim (but with old cell #). Even though they said that it will take 24-48 hours for my new sim to be activated, it got activated in 5 minutes and I received welcome texts from T-mobile. Could not be happier! It was no hassle at all. Additionally, T-mobile gave me 1 month of free usage in prepaid. It has been almost 1 month that I saving around 10$/mo with this prepaid connection, I have faced no issues.
