O2 SIM Only Deals

O2's journey in the UK is a story of growth, innovation, and keeping people connected. Back in the mid-80s, O2 started as Cellnet, one of the UK's first mobile networks. It has since transformed into the sleek, blue O2 we know today.

O2 quickly embraced GPRS and 3G, opening the door to mobile internet, and even rocked the boat with bold unlimited data plans. The company kept pace with 4G's lightning speeds and is now a player in the 5G revolution, promising hyper-fast connectivity and a glimpse into the future.

With exclusive perks like priority access at events, free WiFi hotspots, and device discounts, O2 are passionate about making your mobile life richer and more rewarding.

From brick phones to blazing 5G, O2 has come a long way. They have consistently pushed boundaries, offering affordable plans, reliable connections, and innovative services that keep us connected and entertained.

O2 runs on its own mobile network infrastructure in the UK. Its core network is responsible for routing calls, texts, and data between users and the internet. This ensures efficient routing and helps maintain control over network quality.

O2 operates across various frequency bands, including 4G and 5G, to provide high-speed data services. They are also actively investing in expanding their 5G coverage throughout the UK.

O2 offers unlimited data on 30-day, 12-month, and 24-month SIM-only plans. These plans come with unlimited minutes and texts, as well as 5G. However, the longer-term plans work out cheaper per month. So choosing a 24-month unlimited data plan will cost less per month than a 12-month one, but choosing a shorter plan will mean you are not committed for so long.

With a 30-day SIM Only plan, you will pay more monthly but can change your plan anytime. It is a choice between cheaper unlimited data for longer or a little more expensive per month for a short-term option.

Some of the 12-month and 24-month of these unlimited data options also come with access to the O2 Priority app, a free subscription to Apple Music, plus another freebie of your choice, such as Disney Plus or Audible.

You can roam all you want in most EU countries with your minutes, texts, and up to 25GB of data, just like you are at home with no extra charges or sneaky fees. However, if you want to send pictures, be prepared for a 65p charge per message.

If you want to roam beyond Europe, some plans let you roam the world without a data cap (within the 650GB fair usage limit). Just be aware of O2's traffic management - high data hogs might experience slower speeds!

If your UK allowance tops 25GB, your Europe roaming limit is also capped to 25GB. Use all 25GB before being charged £3.50 per extra GB until you use up your UK data, come back home, or your bill rolls over.

Absolutely! O2 has been ramping up their 5G rollout across the UK, and you can enjoy blazing-fast speeds in many areas. Getting 5G starts with your device. Check if your phone supports 5G bands, as older models might not be compatible. Most recent flagships and mid-range phones released in the past year or two should be good to go.

You can check their coverage map to see if your location is covered.

Even if you have a 5G phone and are in a covered area, you will need a 5G-enabled SIM card to access the network. Luckily, most new O2 SIM cards come with 5G as standard.

O2, like most mobile networks in the UK, conducts credit checks as part of their assessment process when taking on new customers for pay monthly contracts or SIM Only plans with longer durations (e.g., 12 or 24 months).

However, there are still options even with a bad credit rating:

• Prepaid SIMs: These don't require a credit check and offer flexibility with no contracts or upfront costs. You top up your credit as needed. O2 offers various prepaid SIM cards with different data allowances and bundles.
• Shorter contract SIM Only plans: Some 30-day SIM Only plans from O2 have been known to have more relaxed credit check requirements.

O2 has your SIM needs covered with standard, micro, and nano options. Their SIM pack has perforated edges that let you pop out the perfect fit. Check your device manual or look at your existing SIM to choose the correct option.

If you have an older device, you can pick up a free SIM adapter from an O2 store that allows you to use a nano or micro SIM in your device.

Some phones use the cutting-edge eSIM – a digital SIM built right in. O2's eSIM stores your connection info directly on your phone. It is secure, lets you juggle multiple plans, and feels like future tech in your pocket.

To move to an O2 SIM-only deal with your number, you will need to:

• Choose an O2 SIM & temporary number.
• Text "PAC" to 65075 from your old number. It's your magic key code!
• Supply O2 with your temp number, PAC, and old number. 02 will make all necessary changes to keep your old number on your new 02 SIM-only deal.

If you are currently tied into a phone contract, check for sneaky exit fees in your old contract if you want to leave before it expires.

Major UK cities and towns witness exceptional O2 coverage, with robust 4G and blossoming 5G accessibility. While coverage in more rural areas might be less expansive, reliable 3G and 4G connectivity covers the most populated regions. However, 5G availability may be limited.

O2 champions robust data speeds nationwide, consistently surpassing 20Mbps download averages on 4G, with 5G reaching up to 10x faster speeds in designated locations. However, location-specific factors and network congestion can impact individual experiences.

According to Ofcom, here's the deal with O2's customer service: they are not setting the stage on fire, but they are a solid, dependable choice.

• Complaints below average: Fewer folks are grumbling compared to other big UK networks, which is always a good sign.
• Network satisfaction? Just alright: Not the best, but not rock bottom. Think comfort rather than a thrilling ride.
• Complaint handling? It could be better. 60% happy isn't bad, but it's not exactly delivering a high level of joy. Still, it's above average and on par with Three and Virgin Mobile.

Remember, customer service is just one piece of the mobile puzzle. O2 offers solid network coverage, good data deals, and plenty of free perks.
