    @tescomobile I've been on calls for hours to get help, online message and went in store. It's going to cost me £280 to get out of this contract. But I will move back to EE. Reported to ombudsman and left as many negative comments on all review sites.

    @tescomobile hi my phone keeps dropping off 4G and the only way to get it back is to reboot my iphone. I try resetting my network connection by turning mobile data on/off to no avail.

    @O2 @Guard_Amos @tescomobile I always reset my mobile data, even restart my phone. The signal is slow everywhere I go weather it be internet or calls! I don't want to have to pay £400+ to change provider either!

    @tescomobile my daughter is in Italy and her phone isn’t able to join a network- can you help please?

  • Pauline54232922 Pauline Turner #pigoneer (@Pauline54232922) reported

    @tescomobile @accessibleweb @tesconews Are Tesco not putting up their rates? They're pretty cheap anyway. I'm a very satisfied customer. £7 a month. Wahey!

  • ThisIs_soph Sophie (@ThisIs_soph) reported

    @tescomobile To be fair, I would switch if you guys had more network coverage. Do we get clubcard discount 👀
