Calls are very inexpensive and usually loud and clear , not perfect as occasionally sound is very faint and once a call broke up with very loud crackling and bangs . Considering the distance involved these problems are rare and call quality is generally excellent.

Great service from Martin when experienced problems.prompt, simple instructions. Great value

I tried to get the code but every time I receive the wrong code so I couldn’t top up my credit. Finally II thought I managed to top up the credit however I still can’t use it. I am abroad therefore I am in urgent need of using the telephone so please sort it out as soon as possible thank you.

It's so easy to phone and especially phone to mobile numbers in Japan. You don't need to dial a long mobile numbers.

Great service great rates to landlines Australia

Good quality connection. Very competitive rates.

Fast & Clear connection everywhere!
Great prices and good sound qualities!
Thank you! My Tello is my favorite app to connect easily with the world!
Best wishes for a great future!

Not to blame Mytello but calling Iran is very difficult atm

I call Europe from Canada and Mexico and it works well. The only problem was with credit card payment in Mexico. Also my last payment in Canada had to go through PayPal. Otherwise it works well.

Easy to use app. Transparent and very affordable pricing. No hidden costs and excellent customer service.

My Mytello experience was great because the numbers are programmed into a system and it automatically connects with just one touch of a button. The call goes straight through and the clarity is amazing.
The price is also amazing and can’t be anymore cost effective and reasonable and better than your regular phone company. You can use a cell phone or land line and it works great.
The customer service is also great. When you need to add another number or phone it is taken care of in a very timely manner. It has been great to reconnect with relatives in another country for a price you can afford.

Low cost and it works.
However call quality can be improved.

My credit runs out faster than Mytello advertised.

In addition, NZ to UK calls drop out frequently. I've asked a UK company to call me back after the first 3 Mytello calls were unexpectedly cut off.

My international calls go through every time. They are as clear as a local call. I use mytello whenever WhatsApp is not an option. The pricing is very affordable with easy use and quality calls.

Got sufficient credit but operator speaking czech sems to be telling me not enough & hangs up

Effective and easy to use app. Good call clarity. Reliable. Easy to top up.

After an initial glitch where, despite opening my Tello app and selecting a contact, my US Verizon phone made the call.

After that, Tello worked fine - easy calling, and voices were clear.

For cheap calls and to replace Skype when no internet is available, application is doing the job

Very good, very good
