Customer Reviews
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.
Mostly good, one small issue
I decided to switch to O2 and got one of their 5G SIM cards. The delivery was quick, arrived in 3 days, and the activation was seamless. Network coverage in my area has been strong, and the data speeds are impressive for 5G. I did notice that the website can be a bit slow sometimes, especially when navigating through the different plan options. It wasn't a major problem, but it could definitely be snappier. Customer service was helpful when I called with a question about my first bill.
Consistent service as always
I've been with O2 for years, this time I upgraded to a new mobile broadband plan for my tablet. As usual, the process was smooth. My previous mobile broadband was reliable, and this new one seems to be keeping up that standard. I appreciate the consistency; it's why I keep coming back. The network reliability has always been a strong point for me.

Share tips, ask questions & help fellow shoppers save more
Anyone know if O2 does student discounts for their SIM-only plans? My current contract is ending soon and I'm looking to save some cash.
Trying to compare O2 with EE for a new phone contract. Is O2's 5G coverage any good? I'm in Birmingham.
Can I keep my old phone number if I switch to O2? Really don't want to deal with changing it everywhere.
Does O2 have any special offers for existing customers? Like if I want to upgrade my SIM-only plan to a bigger data bundle?
hey, thinking about switching to o2. how long does it usually take for a new SIM to arrive? trying to get it before next weekend.
Thinking about getting one of those refurbished phones from O2. Are they any good? Worried about getting a dud.
