Is Plusnet Mobile a good network?

In terms of value for money and the deals on offer, Plusnet Mobile has a lot going for it. Prices are really low, plans are super straightforward, and because it uses EE’s network, coverage is brilliant. It’s even better value if you have Plusnet broadband, too.

There are some drawbacks, however. There aren’t any unlimited data plans – the highest on offer is currently 50GB per month – and there’s no 5G just yet. The range of deals is also a bit limited: they’re all one-month SIM-only plans, with no longer-term deals or phone contracts. You won’t find many benefits beyond your airtime either – no app subscriptions, no priority tickets, and poor roaming outside of the EU.

If all you’re looking for is a cheap SIM deal with none of the faff, Plusnet Mobile is a great choice and well worth considering. But if you want a little more from your mobile deal, you might be better off with a bigger (albeit more expensive) network like EE or O2.

What SIM-only deals can I get from Plusnet Mobile?

Plusnet Mobile offers a tidy little selection of great value SIM plans.

Data allowances range from 2GB to 50GB per month – though the exact choices available can vary, so do run a comparison to see the current offers.

All have unlimited texts, and most have unlimited minutes too (or if not, you’ll get at least 500 minutes per month). Plusnet Mobile SIM deals are all on 30-day rolling contracts, so you can switch up your allowance or cancel completely whenever you like.

You’ll also have access to bolt-ons if you run out of allowance in the month.

What benefits does Plusnet Mobile offer?

Plusnet Mobile is a little light on benefits – instead, it focuses on just saving you money with cheap SIM deals. The extra benefits you can get include:

  • Extra 2GB data per month if you’re a Plusnet broadband customer
  • Smart Cap, so you don’t overspend outside of your allowance
  • The Plusnet Mobile app, to help you manage your account easily and securely

How to choose a Plusnet Mobile SIM-only deal

Finding the right SIM deal for you - whether it's from Plusnet Mobile or another network - couldn't be easier. Have a look at the deals in our comparison table, and pick the one you like best. 

You can adjust the filters at the side to only show the SIMs that fit what you need, and can compare Plusnet Mobile plans with those from other networks too. When you spot one you like, simply select it, and we'll take you straight to the provider's website so you can order it.

When you're comparing, think about what's most important from your deal:

Data allowance - How much do you use 4G mobile internet? If you only use your phone to scroll through Facebook, browse the web a bit, and use WhatsApp, you'll be fine with a small allowance. On the other hand, hungrier users who stream on the go, use their phone for work, or download large files may want 10GB or so per month. Most of us, however, will find a data allowance between 2-5GB suits us perfectly.

Calls and texts allowance - Think about how much you make calls on your mobile, and how many SMS texts (not WhatsApp or Facebook messages) you send in a month. Very high allowances are available from Plusnet Mobile for quite low prices, so getting enough for your use should be easy.

Contract length - With SIM plans, you usually have a choice between 30-day or 12-month contracts. Longer contracts generally have lower monthly costs, while a 30-day one can be changed at any time. It's worth going for a 12-month deal if you're happy to commit for a full year - though if you want a bit of flexibility, so you can change your monthly allowance or switch networks entirely whenever you like, go for a one-month SIM instead. (These aren't available from Plusnet Mobile, however.)

Price - On a budget? Set a maximum monthly price using the filter at the side, or sort all the deals by cost to see the lowest-priced ones first. See the section below if you need a bit of help finding the cheapest possible deal.

Can I use my Plusnet Mobile SIM abroad?

Yes. All Plusnet Mobile plans include ‘roam like home’ in 40+ EU destinations, meaning you can use your normal allowance as if you were at home in the UK, with no extra charges.

Outside the ‘roam like home’ locations, you can use your Plusnet Mobile phone, but it’s expensive. In some places, your 4G data will cost as much as a nasty £6 per MB.

There aren’t any international bolt-ons to bring that down, either, which many networks offer. You can set a Smart Cap to make sure you don’t overspend, however.

What's the cheapest Plusnet Mobile SIM-only deal?

The cheapest SIM deals have lower allowances, are often on longer contract terms, and may be missing some of the features and extras of a more premium SIM plan. Existing customers can sometimes snag even better deals too.

To find the cheapest Plusnet Mobile SIM option that suits you, just use our comparison table. Narrow the deals down with the filters, then use the 'sort by' toggle to order them by monthly cost. This will push the cheapest deals up to the top so you can see them first.

Can I get unlimited data with a Plusnet Mobile SIM?

Unfortunately, unlimited data SIMs aren't available from Plusnet Mobile. For unlimited data, you may have to go for a different provider. See our guide to unlimited data deals for more info on how to find a deal.

You can, however, get a Plusnet Mobile SIM-only deal with a high allowance. Just sort the comparison grid by data allowance to see the heaviest plans at the top - or choose a minimum monthly allowance in the filters.

Can I keep my mobile number if I switch to a Plusnet Mobile SIM-only deal?

Yep, you can keep your phone number when you switch mobile networks, regardless of which network you're switching to or from. It's surprisingly hassle-free to sort out, too.

All you need to do is sign up to a new deal, then contact your current network and ask for a PAC - a porting authorisation code. Give it to Plusnet Mobile once you have your SIM, and the number should port across within a matter of days.

Do I need an unlocked phone to use a Plusnet Mobile SIM?

Yes, your phone needs to be unlocked - or locked to Plusnet Mobile - in order to use a Plusnet Mobile SIM card.

If you bought your phone outright from a retailer, it should already be unlocked and you have nothing to worry about.

However, if you're using an old phone that you got on a contract, it may be locked to your former network. In that case, you'll need to get it unlocked - but don't worry, as this is easy enough to do.

All you have to do is contact the network it's locked to, and they'll sort it out - sometimes free of charge. They may give you a code to enter, or might be able to it remotely. Your phone will be unlocked and ready for a new SIM in a few days' time.

Other SIM-only networks


You could also trade in your current smartphone and put the money towards one of the newer models. It's a quick and easy process with Depending on what model you have, and how intact it is, you’ll be surprised at what you can get.
