Sorry but my Dutch is niet goed to discuss this kind of topics. Seeking advise: i had to buy a new phone and opted for xiaomi Mi a3, a global model sold at bol.com. I went to a tmobile shop today to get a new card since my previous phone has been lost. After inserting the simcard, no netwrok /internet although the details on simcard are recognised. The guy from Tmobile told ot be get in touch with a phone seller.
i found some information that sometimes APN settings need to be adjusted manually, this didnt help. I swtiched off and on between 2g/3g/4g and 2g/3g , no success. Visited another t-mobile office in my city, a guy tried to fix an issue but no success, didnt ask for any help of colleague. I dont think calling to a client service would help me. I tried to install the network manually but it says neither 2g no 3g/4g is available. Do you know if there is solution or i just better return this phone and buy something more well known over here?
