Hi Phil52 and welcome to the eForum
There could be a number of reasons for your SMS arriving late. The number one reason would be that your SIM is out of date on the network. To fix this just pop your SIM into a mobile phone and perform a manual roam. To do this you'll just need to go into the network selection part of your phone and select the network manually.
Give this a try and let me know how you get on.
The Pay as you go mobile phone SIM should work in the dongle fine. You'll just need to change the APN details to:-
APN - wap.vodafone.co.uk
username - wap
password - wap
Be aware though, this method will use your credit faster than on a mobile phone
Thanks
