Glad I Changed Provider
They Were Very Helpful From Day One. Took My Number With Me & They Sorted Very Quickly. If You Need Help Just Give Customer Service A Ring & They Just Can Not Do Enough To Help. Highly Recommend To Anyone Cheap Calls On Monthly Or Pay AS You Go.

Excellent service with my phone.
Excellent service with my phone however had difficulties with my wife's phone which would not port contacts. Never did resolve so gave up and left? Shame because lost the £5 credit and £3 setup so only 4 stars.

Simple & straightforward
Create your own package from the options provided, make payment and that's you set up; and with the app you can monitor your usage & then change your package accordingly. No bother.

Great Service.
I can recommend the Customer Service. I speak to Customer Service without going through a lengthy procedure of pressing buttons. Problems are dealt and resolved without undue delay. The service provided is very cheap and great value for money. My only gripe is the sometimes poor coverage in parts of my home county, Norfolk, but Tello do their best,

V happy with them
Polite, efficient and helpful customer service. I've had transferred my number from a dodgy mvno. It all went smoothly with my number being active much sooner than promised / expected. Very pleased with the quality of their service, multitude of options available. From my own experience the internet is just as fast as on the main network (3) while the combined UK package with cheap international calls are making it almost perfect. The only downside is the absence of roaming service (incoming calls), but for calls it can be sorted by having them forwarded. Hopefully roaming will be introduced fairly soon.
