Hi,
I've recently purchased a new Sure Signal to replace our old one for our small business office. However, I'm the only one who seems to be able to use it. One colleague gets 'not registered on network', despite having 4 bars of signal, and other colleagues only have Vodafone WiFi calling. This wasn't the case on the previous Sure Signal, as everyone had full bars and didn't have to rely on WiFi calling. Any ideas?
