    @tescomobile @BBCTheOneShow But you don't have a network, you are just piggy backing off Vodafone.

  • AnnReyn75876642 Ann Reynolds (@AnnReyn75876642) reported

    @tescomobile It says a local.mast is not working as it should. But this signal here is hit and miss all the time. Every day.

  • DisabilityBy Stop Disability Hate (@DisabilityBy) reported

    @tescomobile any idea when the network problems are going to be resolved? Impossible to send or receive texts for at least 4 days now.

  • _StaceFaceH Stace. (@_StaceFaceH) reported

    Hey @tescomobile how long should it take for my number to port from another network to you if done on a Friday evening please? Was told not to put new sim in phone until its switched over. This was done in store.

  • Peter14229846 Peter (@Peter14229846) reported

    @tescomobile Haha no chance. I moved to EE had no issues since it’s a little more expensive but I am fine with paying extra for a better experience

  • djellicon Djellicon (@djellicon) reported

    @tescomobile @feralfox34 A you are just another cog in the big network, B it's irresponsible to use swearing to promote your ****. You see it's about appropriate communication via targeted mediums, children at some ages will copy, with no appreciation for situation, please promote kindness not lazyness.

  • TheTethernator Altcoin Scientist (@TheTethernator) reported

    @tescomobile I was with this company for 7 years, I went to renew/upgrade a contract with them and they offered a deal of iPhone 7 on a 3 year contract. I asked can the term not be reduced because I’m a loyal customer or can I pay less each month? They took off £1/mo. Terrible company. AVOID

  • Siorsid Siorsid (@Siorsid) reported

    @tescomobile I left ages ago because you were never interested in helping when the signal went down. Now with Sky using same O2 network & give free data when signal drops. I get 4 lines with 2gb & 1 with 8gb = £24 per month. And all data roles over. Beat that & I'll come back to you.

  • LFC_KloppChamps 🔴⭐️⭐️⭐️Carl⭐️⭐️⭐️🔴 (@LFC_KloppChamps) reported

    @tescomobile Do you actually have a network of your own? When it comes to deals I’m usually quite savvy and not once has your deals ever ever being better than rivals and to top it off you tie people into expensive lengthy contracts
