Poor mobile signal

The service on my mobile has not been great while we have been in France, it cuts out and changes to another provider and then comes back for no reason I can see. Today has been bad as twice I was in the middle of making a payment and lost it. This is my third attempt to blip. We had a lovely cool wait at the vets and Hetty got her tablet and paperwork stamped, so ready for ferry. It reached 36c today and still at 30. The light breeze makes it better than last night but I am getting lots of bites and now have lots of blotches. Problem with getting onto site and needed to phone the remote help line again. While I was talking to them two French motorhomes arrived and were telling hubby to move away from the entrance, there was nowhere to go and he needed to wait until they opened the barrier remotely. Now we have an English couple next to us and they have been arguing since they got here. It feels like we need to go home.
