Needs my cell # to work. WHY? Has never worked on 4G/5G mobile data.

Updated Aug 21/2026
For version 5.10.0
Still doesn’t work for core function of making or receiving calls on a 4G or 5G data connection; Never has worked for this. What bug fixes?

Updated June 1/2025
For version 5.7.1
What bug fixes? Still doesn’t work for core function of making calls on a 4G data connection. (Does work on WiFi now). To be clear, phone says it’s on 5G. Shouldn’t this app still work? Or it’s faulty by design, to use outdated 3G/4G only, that cell providers don’t use anymore.

Updated Feb 15/2025
After 5.5.0 update.
Now WORSE THAN AWFUL
Both Wifi only and 3G/4G only don’t work. Useless app.

Updated July 19/2024:
After 5.1.0 update it’s STILL AWFUL.

Doesnt work at all using 5G data on the mobile phone. This is the only connection that would be really useful at all. (wifi now works; piggybacking on cellular cellular voice line worked prior; 2 out of 3 is still BAD).

Original review Dec 2023
This app doesn’t work on any type of data connection on the phone, despite Vonage itself being a VOIP service. The app has options to operate on wifi data or 3G/4G cellular data, but they won’t work. (using a new iPhone). Worse, the first screen of this app insists on getting my cell number. Else I can’t sign up. Why? One should have to supply a mobile # only if one wants to have Vonage calls piggyback on the existing mobile #. A VOIP service needs another phone number to make calls as it’s starting configuration ….WHY????!!! It works only with my existing cellular number. (The calling option of “cellular” appears to use only the mobile phone number and cell phone calling plan). I want to use only a data connection for Extension calls, either wifi at home, or mobile data when traveling (bought with a esim). Yet this app won’t work with either type of data connection. This is completely useless when traveling, when the cost effective travel sims are data only. I think the solution here is to just switch to any number of other virtual phone number services/apps that run on data/iPhone, and cancel Vonage itself. along with the archaic concept of a “home phone” tethered to a physical location at all.
