My mom recently passed away so I’m cancelling her plan with TMobile. She has an iPhone 13 and Galaxy S21. I was hoping to keep her phones for sentimental reason but would they be usable without a carrier if I’m only connected to WiFi? Would it do everything it does now with just WiFi? I was also hoping I could set up a WiFi number or something because I still text her numbers occasionally and would like to continue doing that without some stranger getting them lol I was thinking I could text the iPhone via iCloud email but I’m not sure
