I moved to New Haven from Ottawa 1.5 years ago. I noticed the US “big names” seem only worth it if you have people on a family plan. I’m currently on Mint Mobile (unlimited) and have no complaints! It’s been great and their international roaming is pretty good too. My old phone was broken so I had to buy one anyway so I’m not sure if there’s better plans but it seems Mint has great offers compared to what my friends are paying.
