- Put your sim in another phone (if you have one) for a few days and see if the calls come through
- Get a new sim (call customer services or go into a shop) which rules out if the sim is faulty

Thank you again, I don't have another phone but I will try the O2 Shop later this week. I did try and call customer service but they are too busy, saying that wait is more than 15 minutes and then the lines just hangs up. I guess they don't want people to wait. But thank you. Your advise is much appreciated.

I just moved from o2 to Smarty on the Three network last week and was able to make calls to all networks including o2 but friends who are on o2 could not make a call to me they got a message "calls to this number are not being connected". After much fafing about with Smarty and trying to get o2 to look into it I got a call from an o2 engineer who had fixed the problem. He said that my phone number originated with Vodafone ( that was the very first provider I used when I got my sim) and that when o2 ported my number over to Smarty they added a couple of extra digits on my routing number. They do this for o2 numbers apparently in order for them to work, but should not of done with my number. Now I can receive calls from o2 sims. It took a lot of persistance with Smarty to get them to investigate this properly, but it paid off in the end. I almost gave up and changed back to o2.
