I was out of contract so I decided to try the SMARTY offer I found. I activated my sim on the 15th March 2023 after it arrived by post and using the SMARTY App, I also entered my PAC code as I wanted to keep my old number. My old sim stopped fuctioning shortly after and I replaced it with the new SMARTY sim. The SMARTY app stated that my new network would be ready by 5pm and an e mail would be sent to confirm this. All going well so far. 5pm arrived and there was no e mail, no phone service and no 5G. At 5.45pm I contacted SMARTY via the live chat and I was taken through a number of worthless checks: it's my device, clear my messages??, put the sim in another device, take the sim out/put it back in. Eventually I was able to make out going calls, but then I discovered that any incoming calls were being treated as an "incorrect number please check and try again", it was like the number didn't exist dispite being able to make out going calls. I kept going back and forth on live chat until 8pm when evenually live chat closed for the evening and the fault was not resolved. This morning on the 16th March I have found that I can now receive in coming calls and make out going calls but 5G is still not working. I contact SMARTY through live chat again and we spend sometime going back and forth with another number of worthless checks, there is no 5G in my area "err yes there is", put the sim in another device, change the APN settings, faulty sim, too many people using the same 5G mast, work being carried out on the mast. It just couldn't be resolved. Today at 5.30, 16th March I dicided to cut my losses and close my account and asked SMARTY to provide a PAC number as I'll look for another network provider only to find that this is going to take another day for them to issue this. Don't waste your time, poor network service, poor customer service, poor me.
