The technical team has identified the root cause of the issue impacting 2G, 3G and 4G services across the UK. They are now working on a possible solution. At the moment we do not have a time frame for when this issue will be fixed but as soon as we get more information we will make sure to keep you in the loop.
Your best option for data service this morning is to use wifi where available -- many stations have it and so do most branches of mcdonalds but there are many other places.
To find local wifi services, use the coverage checker https://giffgaff.com/coverage-and-service#coverage
Note that public wifi may not be secure so should probably not be used for banking etc. If you can't wait, you may need to use services at a cash dispenser, visit a branch or telephone the bank.
To find when the problem is fixed, check the opening post of this thread (it's easier than wading through the comments).
Or, check the status at https://giffgaff.com/coverage-and-service#network but again you must ignore any "normal coverage" statements and read only the first line after the "live results" heading.
