IP phone with 3g support. Are there any?

Question

Asterisk

Good afternoon!
Looked around the search engines, but did not find it. You need an IP phone to connect to asterisk with the ability to work via a SIM card. In the office, let's say voip works on wifi, and outside the office on 3g. I know about smartphones with applications. Maybe there are hardware solutions?

We took this and tested it - it seemed to work, but it looks too old
