I have been with EE for many years and went over to a SIM only contract 3 or 4 years ago. Kept it rolling but a great deal just came up as an upgrade option - an extra 7GB of data for an additional £1 a month. I put in for the upgrade through my EE app - completed in about 2 minutes and additional data added immediately. Really simple, clear explanation, no catches, great deal and very efficient service. Thank you EE, every reason to remain a loyal customer!
