I live in Canada and i went to use my British phone yesterday and it would not connect to network. I immediately got in touch with Tesco via messenger and after considerable time was advised it was a problem at the UK end. They(Tesco) have since corrected the problem however i still cannot connect as the Sim card needs to be in the UK to reactivate. My annoyance is I probably could mail the card to UK and get it corrected but if it is not done before Sept.19th i will lose my credit on the phone (close to £20.) Takes more than a week for mail to get to UK. Bearing in mind this is all because of an error made by Tesco. I have tried to get the time frame extended but to no avail. I normally travel to UK twice a year but due to Covid i am unable to do so. I am very disappointed with Tesco for their lack of consideration. How they rob people of money and get away with it. I certainly will be looking for a different phone carrier when i managed to get back to the UK.
