I write this review regarding my recent experience with Tesco Mobile. I have just ported two numbers from Sky Mobile. Our phones do not have physical SIM card slots so we use eSIMs. On calling their call centre initially it was quite clear they didn’t know anything about esims. I was asked to call in the store. I called in to discover that the assistant forgot his keys to the cupboard housing his laptop so had to go back the next day. This I believe paints a good picture of the level of competency I experienced. I noted that with Tesco Plus (which I have) there is a double data offer. I asked if this is on the two phones and he confirmed it was. On this basis I entered the contract. My wife’s phone ported over really well. Mine didn’t. Sky gave just one PAC code for the two numbers. This is apparently a new way of doing things which again Tesco were unaware of. My number was lost for three days and I nearly didn’t get it back, this was a worry as I use the phone to run a small consulting business. Tesco just blamed me and Sky. I got through to a manager Suki, who just refused to help point blank. It was both our faults for not getting two PAC codes however it turned out my phone did port over but one of the advisers admitted there was a fault at their end preventing my number to fully port. However this is not the main reason for this review . Despite the confirmation after my number was fixed they stated that only one number would receive double data. I explained that double data in the two phones was confirmed prior to contracting. I believe this should stand in conjunction with consumer rights. Even getting involved with high level complaints Tesco Mobile has refused to honour this contractual term. Eventually I was offered an alternative, to except a small good will gesture (that won’t cover the purchasing of the extra data) or leave the contract. Given the competency level of the business I certainly don’t want to go though another porting. I accepted the goodwill gesture for the inconvenience caused but said that I was still annoyed that they were not honouring the agreed contract. They did not respond to this. I thought I would pass on my experiences as no doubt they are ducking out of responsibility elsewhere. I believe a lot stems from poor staff training as they are not up to date with tech or current offers.
