Best SIM card deals for kids

18th March 2021

Choosing a SIM only deal for a child or teenager can be daunting, so to help you out we've picked some of the best deals on the market for youngsters.

In selecting these deals we've considered several factors that are very important when choosing a plan, including: parental controls, spending caps, contract lengths, price, and additional extras.

So without further ado, here are the best SIM Only deals for kids and teenagers.

1. Three

Unlimited Snapchat, Netflix, Apple Music and More

Three are worthy of consideration because they offer Go Binge plans which include unlimited streaming on Apple Music, Deezer, Netflix, Snapchat, Soundcloud and TV Player. Go Binge comes with all Advanced plans with 12GB or more of data. At the time of writing, all new phone and SIM Only plans are Advanced ones, so you only need to worry about the data limit.

You can also pick up truly unlimited data plans on Three with no speed caps on Pay Monthly and PAYG plans.

Spending caps are also available so that users can't use more data than their monthly allowances, and it's possible to block calls to numbers outside of a bundle (such as premium numbers).

2. Tesco Mobile

Child Filters and Capped Contracts Turned On

If safety is one of your main concerns then Tesco Mobile, who use O2's network, are a good choice to consider.

By default all users can only access content designed for under 18-year-olds. This can only be turned off via an online form or by credit card verification. Spending caps are also available and can be setup either when buying a plan or at any point afterwards, avoiding any unexpected high bills.

Unlimited Social Networking and Video/Music Add-ons

VOXI mobile uses Vodafone's 5G mobile network and users can enjoy endless social media on Snapchat, Instagram, WhatsApp, Facebook, Twitter, Pinterest, Viber and Facebook Messenger. As well as Endless Video on YouTube, Prime Video, Netflix, My5, TVPlayer and UKTV Play. But it doesn't end there because for £5 a month you can get an Endless Music pass which lets you use unlimited data on Spotify, Apple Music, Tidal, Deezer, Soundcloud, Amazon Music Unlimited, Prime Music and Napster.

Parental controls are also available and contracts are essentially capped, in that if you run out of data you have to manually buy more or wait for your plan to refresh, so there won’t be any unexpected bills.

5. EE 

Swappable benefits and free subscriptions

Currently EE are offering BT Sport free for 3 months, MTV Play free for 6 months, and Apple Music free for 6 months on SIM Only plans. In the case of all of those except BT Sport the data you use also won’t come out of your data allowance.

If you wish to continue these beyond the free period Apple Music costs £9.99, MTV Play costs £3.99, and the BT Sport app costs £15 a month.

On top of that, some EE SIM Only plans also come with ‘Swappable Benefits’, which let you select one or more free benefits, including an Amazon Prime Video or BT Sport subscription, free roaming in more locations, or the ability to use data on select music, video and gaming services without it coming out of your allowance. So this is a great way to keep kids and teenagers entertained without racking up big bills.

Parental controls are also available, and you can enable a cap on the account to limit spending.

Considerations when choosing a deal

  • Spending caps

These are caps offered by some networks which prevent you spending more than a set amount, so there’s no danger of your child accidentally racking up big bills. Some networks have spending caps set by default whilst others require you to manually switch them on and the rest don’t offer this option.

  • Parental controls

Another thing you might want to consider, especially with younger children, is parental controls. Basic controls, such as blocking adult content, are offered by a number of networks, and you can block in-app purchases in the Google Play Store or App Store.

  • Allowances

When buying a SIM deal for a child or teenager you should consider how much data and minutes they actually need, and how much you’re comfortable with them using.

If their phone is largely to be used as an entertainment device – for example to watch YouTube or Netflix videos - then you might want a high allowance for them, especially if much of this usage will be happening away from home. In that case, consider 10GB or more.

But if you want them using it as a way to stay in touch with you then a far smaller data allowance should be adequate. You’ll still want some, especially if you plan to communicate with them by WhatsApp or the like, but 2-3GB should be plenty, and will limit their ability to over-use their phone.

  • Pay Monthly or Pay As You Go

Pay Monthly plans offer better value, come with additional extras not available on Pay As You Go and eliminate the need to top-up on a regular basis. But stick to a 30-day plan with spending caps and SIM Only is just about as flexible and as difficult to over-spend on as Pay As You Go.

Pay As You Go plans give you total control over your child’s usage and spend, although one consideration is that your child may run out of credit and be unable to contact you.

  • Contract length

It's also worth considering how long you want to be tied in for. If getting your child a SIM plan is more of an experiment, or if you’re not sure what kind of allowances to go for, it could well be worth going for a 30-day plan. This gives you the flexibility to easily change or cancel when needed. However, in our experience, 12-month contracts generally offer the best value for money.
