Maybe this:

or using Regex with this:

A while back I contributed this to the B4A additional libraries:

https://www.b4x.com/android/forum/threads/b4a-and-b4j-phonevalidator-library.94014/#post-594868

It is a simple wrap of google's libphonenumber library and hence is pretty comprehensive (e.g. is country aware) and works a treat.

It is precisely for all these sorts of reasons that the formatting and Regex style solutions are inadequate.

Note this link comes from the google libphonenumber effort which is what is used by my phonevalidator library.

To stay up to date you need to regularly update the libphonenumber-x.x.x.jar which now stands at 8.10.15 - and update the ...B4A/Additional Libraries/phonevalidator.xml to reflect this

I have updated the phonevalidator library thread accordingly.
