Customer Reviews
Good value, some delivery issues
I ordered a monthly SIM only plan with extra data offer from O2. The sign-up was pretty straightforward on their website and the plan itself offers good value for the data I get. Delivery for the SIM card took about 5 days to reach me in Birmingham, which was a bit longer than I expected, but it wasn't a huge problem. Activating it was simple enough. Customer service was helpful when I had a question about setting up data roaming. Overall, a solid experience, but they could speed up the delivery time a little.
Decent deal for a new customer
I needed a new SIM and found a new customer offer on O2 for a Big Bundles Pay As You Go SIM. The extra data offer was what really caught my eye. It felt like a good saving compared to other networks I looked at. The SIM arrived quickly and was easy to activate. For someone looking to save money, this was definitely worth the purchase. I'm happy with the data allowance for what I paid.
Good experience with SIM only
I ordered a monthly SIM only plan a few weeks ago. The ordering process on the O2 website was pretty straightforward, no hidden steps. Delivery took about 4 days to reach my address in Liverpool, which was within the estimated timeframe. Activating the SIM was quick, just popped it in my phone and followed the online instructions. The network coverage has been solid so far, no dropped calls or slow data, even on 5G. I haven't needed to contact customer support, which is usually a good sign. The plan I picked gave me a decent amount of data for the price, felt like a fair deal overall.
Decent value on new plan
I was looking for a new SIM-only deal and checked out O2. They had an extra data offer on their monthly SIM only plans, which was appealing. The sign-up was easy. I got double the data for the first three months, which really made the value for money stand out. It felt like a good saving compared to other networks.
Fast delivery, easy setup
Got a new monthly SIM only. Delivery was quick. Activation was simple. Network works well. No complaints.
