I've been with Lebara since November and all started well. However, I started to notice in February and March the network was not available in the mornings, not everyday but on one occasion it happened 2 weeks running on a Thursday and Friday in March! Lebara staff were helpful in trying to sort the problem but not solved. I asked for a new SIM and for a week no issues but today, 8/4 no network. I was in exactly the same location on the 7th and all was ok. What's most annoying is it is unpredictable, Lebara say it's my phone but that can't be because if it was a fault on the phone surely it would be everyday. I checked Vodafone's coverage on their website and it says, everytime, all is well but something isn't right and it is either Lebara or Vodafone. I've got to the point where I need a more reliable network so will probably have to leave - was with virgin/O2 for 12 years and never had a problem. Anyone else in HP11 had issue?
