No coverage away from WiFi

[Braddas8121]

I moved to a business plan, in January I did question at the time but was told aerial direct was part of 02 , they would still be my provider and cheaper bills.  Fast forward to May where I have no service when away from WiFi,  plenty data left.  New sim tried no joy. Back and forward still no joy and a mobile which is not letting me call   texts etc away from mobile.  Last update from aerial direct was this weekend and was told that o2 engineers said I had been making calls and sending texts using data. I think one call when probably in range of WiFi  or patchy intermittent signal.  A mobile phone which isn't working away from wifi is a safety concern and frustrating.  Any ideas.  Thanks in advance

As you are with Aerial and not O2 (search the forum and you'll see why) you need to get Aerial to fix the issue.

Unfortunately you've made a huge mistake.

Still getting Billed to 02 , but aerial direct provider...yes I'm beginning to suspect that. Over a month with no stable mobile coverage.  Thank you for your reply
