I set my mom up with Republic Wireless years ago since she needed a phone but doesn't use it much. Now that Republic is merging with Boost, I'm trying to see if there's any better deals out there. It looks like both Mint and Tello say they use wifi calling when available, does that mean they also use wi-fi for web browsing on the phone? It does for Replublic but just wanted to make sure, thank you for any info.
