Great Customer Support Reps, and friendly pricing!

I'll be honest: Tello didn't work out for me — but that's on the technical requirements, not on the company. I'm based outside the US and bought a plan hoping to activate the eSIM remotely. Turns out activation requires connecting to a US tower at least once, so if you're abroad with no US trip planned, this won't work for you. Keep that in mind before purchasing. That said, the way Tello handled it deserves five stars on its own. Their support replied fast, didn't give me any runaround, and processed my refund quickly and without any drama — something many companies could learn from. It's rare to see a provider treat a customer this fairly when the sale doesn't work out. If you live in the US (or can activate there first), I'd genuinely recommend Tello — affordable plans and a support team that actually cares. If I'm ever in the States, they'll be my first choice.

Tello has done everything right

Tello has done everything right. Tello has not copied or tried to reinvent the wheel. Tello just did it right. We thank you Tello! P.S. I recently purchased a new phone (NUU X10) from Tello, everything from purchase to activation, went smooth. We have 4 lines on Tello, 2 numbers ported and 2 numbers new. Our experience with Tello has been the best. Customer service A+. Again, Thank You Tello!
