I need to update my phone. It has too little memory even without any additional apps and with micro SD card installed. The problem is, I need the Wi-Fi calling option available. I would like an android smartphone with 16GB of storage. Currently, there is only one phone with that option listed in the Ting shop, but it has only 8GB. Is it possible that other phones have it but it is not listed on the website? Did anyone buy a phone recently from the Ting shop and had the Wi-Fi calling installed on it? I don't want to go to T-mobile to buy a phone. It seems that getting an unlocked phone is rather difficult. Many thanks in advance.
