The Best Telephone Service Available !
The best, cheapest and most transparent service that allows me to call my wife and children in France from the UK for literally 2 pence per minute. It means I can have a proper conversation with my family at a price that is without question the best available. Thank you Tello. You have made a big difference to the quality of my working life. Kindest regards. Mr. Stephen D. Woods-Shepherd M.Sc., B.Sc. (Hons.).

Well run. Easy to use app. Excellent customer services.
I was with Tello for a couple of years, but left for a better deal elsewhere otherwise I would have given them five stars! Sad to leave as Tello were incredibly efficient, always answered the telephone/webchat immediately and did what they promised. This hasn't been the case with my new mobile company. Bundles last a month and have to be purchased every month via the app or online. You can vary your bundle month by month to suit your requirements. Unused mins/texts/internet can be rolled over if you purchase just before the month runs out. Tello run on Three network, who have really upped their game in recent years. Never had a problem with getting a signal.

Not a heavy user and Tello is ideal for me and the automatic payment when my credit is low means I never run out. Works well for me. Thanks

I joined TELLO early last year because …Its one of the lowest cost services
I joined TELLO early last year because I could just have Pay As You go with out any monthly plan payments. TELLO changed this so now I have to have a plan . They are polite & fast in communications . I like the Company BUT the signal coverage & strength from 'THREE' network that Tello uses is not as good as other of the main suppliers...O2 ...Vodafone...EE Thank you @@@

How nice to have a NO Hassle service provider, unlike others who only want to sell you this week's latest phone. When you have a question you ring, they answer promptly and away you go with an answer.

I'm leaving!
Initially very happy but the recent price hike has made me request my PAC code. As soon as my new SIM arrives I'm leaving to go to a rival network. Whilst with Tello service and coverage was good so no real complaints there. However I get very angry when you sign up with a provider and within months they put the price up. If you think about it, they do this a lot. It's not acceptable and it's happened so many times now that it's not a coincidence.
