iD Mobile SIM only plans are among the best deals available. They provide generous data allowances for a low monthly cost, allowing you to scroll, share, and stream without exceeding your budget.

Why should I choose an iD Mobile SIM deal?

First of all, iD Mobile SIM only plans include some fantastic extras like data rollover. So any data you haven’t used at the month’s end will instantly be carried over for use the following month.

Additionally, iD Mobile allows you to set a spending limit up to £25. If money is tight, this feature will come in handy.

iD Mobile also offers inclusive roaming in over 50 nations, in contrast to some of the major networks. Therefore, using your mobile plan as usual while on holiday won’t cost you anything extra.

Last but not least, 99.8% of the UK’s population is covered by iD Mobile. This is due to the fact that it uses Three’s network, so you’ll never have to stress over being without signal, wherever you may be in the UK

How to find the best iD Mobile deal for me

If you’re thinking about getting an iD Mobile SIM only deal, first consider how you use your phone on a daily basis. If you frequently watch streaming content or send work emails with hefty files attached, you may need a big data bundle. On iD Mobile, you can even get 100GB per month for a reasonable cost, and unlimited data isn’t that much more expensive either.

However, if you spend a lot of time at home on Wi-Fi or don’t use your mobile a lot when you’re on the go, a lower allowance ought to be enough. SIM only plans from iD Mobile start at as little as £6 per month for 4GB.

All iD Mobile SIM only plans include unlimited calls and texts, so there’s no reason to fret about exceeding your allowance. And they all provide no-cost roaming in 50 countries around the world too (EU included).

Coverage area

Three’s network powers iD Mobile. So you can look forward to 4G service that covers over 99% of the country, which is comparable to other big brand competitors like Vodafone, EE, and O2.

iD Mobile also boasts an expanding 5G network, with super-fast speeds available in over 487 areas throughout the UK.

Customer service

Like other low-cost phone networks, iD Mobile’s customer help is only available online and does not include telephone support.

If you have a simple question, you can consult a chatbot or an online advisor. It is accessible Monday through Friday from 9am to 8pm and on weekends and bank holidays from 9am to 9pm.

You can access iD Mobile’s Help & Support page on its website for round-the-clock assistance, which includes helpful hints, FAQs, and guides to aid in troubleshooting frequent issues.

You can also get involved in the well over 50,000-strong online community of iD Mobile, who are eager to assist in problem-solving on the company’s online forums.

Benefits

iD Mobile SIM only deals may not include the same variety of freebies as those offered with larger networks (like O2 Priority). However, there are still some decent incentives that should appeal to most customers.

Data rollover, which enables you to carry over unused data into the next month, is a benefit you may find very useful. You won’t need to mess around with your settings or contact customer service to activate it either because it simply kicks in automatically.

Refreshingly, iD Mobile also includes roaming (unlike many other big networks), so you can use your mobile in 50 locations just like you would at home.

Additionally, if you have a compatible phone and are within the coverage area of iD Mobile’s 5G service, you can get connected to superfast 5G for free.

Roaming

Inclusive EU roaming is still available with all iD Mobile plans. This means that you are free to use your UK allowances in 50 destinations, some of which are even outside of Europe, without having to worry about additional costs.

Contract lengths

You can join iD Mobile on your own terms – the network offers a range of contract lengths which start at 30-day no-commitment rolling deals, 12 month plans, or 24 month plans. It all depends on how much you want to pay each month. Typically, the longer the deal the cheaper the rate, but then of course you’re locked in for more time.

Upfront costs or set-up fees

There aren’t any upfront costs, charges or payments involved with iD Mobile SIM deals. You just need to choose a deal with a monthly fee you’re happy with and then that’s all you’ll need to pay for.

Data rollover

If you wind up with data left over at the end of the month, iD Mobile will conveniently roll it through into the next month. That said, if you find yourself often having data to spare, you may be paying for more data than you need. In this case, check how much data you actually need every month and consider dropping down to a lower amount, which in turn will likely be cheaper than your current bundle.

Tariffs

iD Mobile is a budget network with SIM-only plans starting at only £6 a month.

You can choose from flexible 30-day plans that work on a rolling basis – which means you can keep going with no commitment or cancel whenever you like. If you’re willing to commit for a longer period of time, 12-month and 24-month deals are also available.

Monthly data bundles vary, starting from 4GB per month for low-level users all the way up to unlimited data for heavy data guzzlers.

In addition, all plans include unlimited talk and texts, and you’ll also have the option of changing to a larger or smaller data package with just 30 days’ notice.

Wi-Fi calling

Wi-Fi Calling is a new feature included with all iD Mobile plans. It enables you to make and receive phone calls (or send/get texts) over a Wi-Fi network.

Sometimes signal blackspots can prevent you from connecting to 4G (or 5G), but with Wi-Fi Calling, this is no longer an issue. It provides you with clear phone calls in more locations, so you won’t have to worry about missing that important call if you can’t get reception.

Any calls made through Wi-Fi Calling are deducted from your monthly minutes allowance.

Tethering policy

You are able to tether another device and set up a mobile hotspot with all iD Mobile SIM-only deals.

Any data used via tethering will be deducted from your data allocation if your plan has a data cap.

So you can use the hotspot for as long as you like if you have an iD Mobile unlimited data plan.

But if you do have a certain amount of data to use, you should carefully monitor your usage because streaming content on a device like a laptop could end up using all of your allowance very quickly.

Other networks

If iD Mobile’s SIM only deals aren’t quite what you’re looking for, there’s plenty more to choose from with another UK network, such as:

FAQs

Will I need to sign a contract?

You only need to sign a contract if you decide to get a long term SIM only or pay monthly mobile phone deal. If you’re not interested in committing to a monthly contract, get a 30-day rolling deal instead.

Is iD Mobile connected with Three?

Yes iD Mobile runs its service by way of Three’s powerful network. So you get 99% UK coverage, excellent 5G, and fast connection speeds.

Can I get an iD Mobile SIM only deal with poor credit?

This depends. If you’re interested in a pay monthly mobile phone plan or a long term SIM only deal, then you will need to complete a satisfactory credit check. That’s because you’ll be committing to a payment plan and ID Mobile will need to confirm your credit status. However, if you choose a pay as you go deal or a one month SIM plan, you should be able to sign up with no checks involved.

If I get an iD Mobile SIM-only deal, can I keep my current mobile number?

Yes, keeping a phone number is easy. Get your PAC code (by sending a text to 65075) give the code to iD Mobile when you’re ready to switch and your new network will do all the spring-pulling behind the scenes to ensure your old number is loaded on to your new SIM.
