I really want to like Tello, however there are a few issues that would keep this from being my primary phone service provider. Their rates are better than what I receive now, and if all things were equal, I will have both of my lines with Tello. As of 2026-10-03, I have Tello as my secondary phone number. This number supports voice, and SMS. I will imagine that my iMessage, and RCS communication will carry over my data plan with my primary carrier. For now, there is no data services on my Tellow line. This shouldn’t be am issue though. Since I already have data with my primary carrier, and Tello is intended for voice and SMS services only, there is no need to add data services to the plan.
