So it looks like I'm gonna need to get a phone with wifi calling on tmobile. Grad school I'm going to has horrible reception inside buildings. Verizon has the best coverage, but costs 30-40 dollars more a month. Each cell service is fine outside buildings, but almost all of them lose signal once inside. To anyone that has it and uses it on tmobile, what are your first impressions? And does wifi calling also work with sending and receiving texts?
