The phone service efficiency and the time/cost ratio. I use this service mainly to call from the USA to Mexico. I want to use it to call France, but it is not possible, I don't know why.

I am delighted that I stumbled upon this app. Since then, I have been using it to make international calls to my family and friends, and I am always happy about it.

Great way to communicate with family throughout the world

Very good nice too

Awesome phone service company!!!

I had a different company for years and could never talk to a human when there was an issue. KeepCalling has LIVE support staff to answer any questions. Additionally, the prices are fantastic!

Best Value Never a problem to access & best value for money. I totally recommend using “Keep Calling” for all you international calls. Plus credits never runs out until used 👍🏾

Great services at reasonable costs.

I have been using Keep Calling for many years. Never had a problem. Call charges are so very reasonable. Topping up is simple.

You can call anywhere anytime, the connection is great and the price is unbelievable.

No calling time is added to my account after the charge. My account is still 3 cents left that makes me unable to call.

easy pay and see the plan detatil

Calls get interrupted

Quick and easy , good rates.

It is value for money when you want to call overseas. Easy to recharge, Easy to phone, great connection. Had it for at least 10 years and have been always happy using it.
