Auto-generated from all reviews of this business. For reference only.I've used this service for 4 or 5 years with. Aside from the exceptionally rare blip...exceptionally rare, I have enjoyed this app for local calls, long distance and unlimited data. I've used it, seamlessly, in Canada and the U.S. and it serves me well. If you do have any issues or questions, the service representatives are available almost instantly via the online help feature. Note: I'm not very Tech savvy but they hang in there with me. 😁
I had to get customer service to get started, but the customer service was A++ Now I'm going to test the service for a month to get a better review of my new service plan.
Service worked reasonably well in the beginning, but after a year, it stopped working in Korea, and their head engineer kept blaming it on local carriers and was extremely rude and arrogant, bragging about how he worked for a large telecom before. At around the same time, I stopped getting text notifications when I used to be able to before for verification. Coverage was also spotty in Turkey and Greece. The price might be reasonable, but not anymore for me. The call quality is also poor a lot of the time, where there's a lag.
On arrival in a Roaming country, Fonus would not work. Tech support on their chat fixed the problem very quickly. Great service.
I am leaving this review for fonus technical team. Today my phone was dropping calls because of a glitch of some kind on fonus but the tech Bruce was so knowledgeable and patient to figure out how to make my iPhone on fonus work again for me over wifi connection. I was so happy and appreciative that they figured out how to restore my service again. I had spent some time with the previous tech people who also tried several different solutions for me but without any luck to get it working. This time the diligence of the last technician paid off and completely corrected my issue where" I could not hear the caller nor could they hear me. . I was so happy to have this solved again and have had no more issues with it. I had to give them 5 stars for service & 5 stars for dedication to find out with accuracy a solution to make my phone work perfectly for me again. I am feeling blessed &&enjoying the fonus service once again thanks to their technically superior staff. It is an economical phone to use and mostly works over wifi as well as cellular service.
They stayed with me for hours helping me. Ursula,Sophie and Emilly were very kind and patient with me.
Support walked me thru my issues until it was sorted and was courteous and helpful and didn't make it complicated
Fonus is a Scam if they Tell you you can port your number dont believe them, and customer support is quick but with no results. No Technical support that you can talk to. Don't go with this scam.
Terrible experience with service and especially customer service. Ordered a SIM with urgency (1-3 days delivery) and only after 4 days, upon repeated inquiry turned out that it hasn't yet been sent. (Eventually got it after 8 days.) Asked CS that they reimburse the quick-delivery fee, that was first promissed (but nothing happened), then refused saying that I've got the card eventually. Later (upon complaint) has been told that they will email me when/if they have an update on my request. 1 week passed without an answer.
I had a lot of problems with them. Inaccessible phone numbers, a slow or even no connection, poor quality of telephone dialogues and also, very important: I did not always receive my access codes to authenticate myself with my bank. No compensation despite the obvious problems encountered. And they tease you with "unlimited internet". This is a lie, you have to read their terms of use carefully because I received an email from them warning me that I was using too much data and they threatened to close my account if I did not have a "reasonable" use. It is impossible to talk to anyone, everything happens by chat. And sometimes it's slow. So, no, I don't recommend it at all.
Initial customer service agent was unhelpful but the last one (Ursula) was very helpful! Great ending.
The fonus tech support is the best I have ever experienced! Quick to respond, a real human, and helpful service.
Little ruff to setup but with their help it works fine here in the US now to test on trip to Philippines.
Service via online portal was 1uick easy and my issue was fixed!
Ursula was great in providing remote assistance with setting up everything to get my esim working. Thanks Ursula
The process was a little convoluted but the setup instructions on the fonus email are correct and I got the esim setup in my pixel 7 2nd try. They send the QR code via email and in order to scan it in the app I had to forward it to my wife's phone to scan, there must be an easier way to do that...otherwise the support crew did get back to me quickly, now I'll have to checkout how it works after a long flight to Europe....
We've been happy with Fonus for several years now. We get worldwide coverage and unlimited data with no complaints. Tneir support staff are quick to respond to any issues. We've recommended Fonus to many people.
explained my options for replacing my sim that is currently swimming in the harbour in my phone
I have been using Fonus for a while now, and the experience has been amazing. The support team is excellent, especially Ursula, who deserves 5 stars for her outstanding support.
I’m up tight when my phones not working. Fonus staff walk me through and teach me how to solve the problem. They are super
