Curve 8520 cannot send/receive calls or SMS when in range of WiFi - since foreign holiday

Re-posting this in the Curve forum, where it belongs... hoping someone can help.


Recently the whole family went to Spain for two weeks. All four of our phones (a Google Nexus 4, a BB Curve 9300 and two BBCurve 8520s) worked OK in Spain, connected to local mobile networks, sent and received texts and so on.

 

Since returning to the UK, the BlackBerry handsets have all had problems getting re-registered to our home network (giffgaff, which uses the O2 network, as I understand it). The nexus has been fine from the moment we got back, but the BB handsets are not.

 

The symptoms: when in range of a registered WiFi connection, the phones cannot send or receive texts (SMS) or make or receive calls, when out of range of WiFi, they do (sometimes) succeed. It is as though the WiFi settings are over-ruling the service books / HRT for the mobile network.

 

The 9300 seems to have sorted itself out, thanks (possibly) to an OS upgrade. The 8520s remain basically useless.

 

We have tried: battery pulls, SIM pulls, manual network registration, clearing the service books and re-registering, switching SIM cards between the phones (whichever SIM is in the 9300 works OK, whichever SIM is in the 8520 does not work), OS upgrade.

 

The network shows on the handset screen, and connection is shown as EDGE. But calls do not get connected and SMS messages fail with "too many retries". Attempts to re-register the handset result in a message being received that the handset has been registered but it makes no difference.

 

The network provider (giffgaff) say they have done everything they can, and I should speak to "an engineer" - but it seems very unlikely to me that all three phones suffered a hardware fault while flying home from Spain, and that the 9300 somehow fixed itself. So I'm convinced it is a registration issue, but giffgaff are not exactly confident in their support for BB.

 

So - has anyone ever seen this behaviour before, and how can we fix it?

 

Thanks
