O2 Sim Card Preloaded with UNLIMITED UK Calls, Texts & 4G/5G Data. (Valid for 30 days). No Contracts, No Commitments, No Credit Checks, No Tie-ins, No Personal ID. Simple to renew

This was brilliant. Setting it up was really easy. I spoke to a delightful man on the phone and he worked me through. He then sent a couple of emails that highlighted the steps required. The data has been as promised - really fast. My kids and I were tired of the wifi where we were staying for a break in the UK as they were quite slow and dropped too often. This one was like a breath of fresh air. My boys who had been waiting for ages for their Fifa 2021 to download were pleasantly surprised to see it download quickly. The stability of the network has been a relief too. Will stay with O2 for data after this.

This is the 3rd unlimited data sim, that I have bought. The other two was activated when I received them. For this one I have to send an email with my contact number and it can take 48 hours to activate...

Wi-fi signal good

We bought this for our mobile router that we use in the caravan. It arrived quickly and was very easy to set up (unlike the EE SIM card that we'd originally planned to use from another provider!). We had a question so I emailed the supplier in the evening and the next day I received a phone call and my question was answered straight away - excellent customer service. When we got to the caravan site, which was fairly rural, the signal strength was better than the on site wifi and we were able to use multiple devices to stream, email, access websites etc. One very happy teenager and two relaxed parents!! Would definitely recommend and will be buying again.

We planned a week away in Cornwall and hadn't considered there wouldn't be a solid broadband connection available. Our mobile provider didn't have good (any!) coverage in the area so we needed a solution. O2 apparently had good coverage so we opted for this SIM + Huawei E5576-320 mobile internet device. They arrived quickly and I'm pleased to say did the trick perfectly. Very easy to activate the SIM and good communication from the provider. Will be using again. Thanks!

Sims4Travel. I got the Sims4Travel 100GB deal, and boy it is a deal. C/S got me all hooked up a couple of days before I traveled to Toronto. Landed and straight-away was able to Whatsapp back to the UK, Whatsapp M8s in Toronto, Used Waze and Sygic to drive like a local no problem at all. and MOST importantly: the Mobile Data speed was awesome, No Dead Spot, dropout, lost of signal and speed of DATA connection was far more than sufficient for what I needed. Definitely recommend, as I'm about to either get another one or reactivate this if possible, as I'll be heading back there next month. Thanks again Richie @ Sims4Home/Sims4Travel..

Supposedly takes 48 hours to activate ( which I wasn’t expecting) and still after 48 hours it is not working.

I think this is a good SIM card and good value for money, the only down side is that you can’t top it up, Vodafone is missing a trick here.
