One SIM, all Networks, with the Strongest-Signal roaming SIM from ParentShield.
Simply put, with a full roaming all-network SIM card, coverage can never be beaten. If there is a signal from ANY network, then you will have signal. The ability to roam between networks means there are far fewer not-spots than you will find with any single-network network. ParentShield SIMs are also 2G, 3G and 4G and 5G, so in a phone with all these capabilities, coverage couldn’t possibly be better.
All the major networks provide impressive-sounding coverage statistics for their networks – usually stated in terms of ‘population coverage’. It will be 97-99% or something like that, which sounds excellent, until you lose coverage. And there’s nothing worse than no signal when you need it.
All the four UK networks use different frequencies to connect to your child’s mobile phone. Some frequencies travel further than others and some are better at avoiding ‘cross-talk’ from other signals. So even if two networks are sharing the same mast, it doesn’t mean they will both work as well as each other.
The best solution by far, if you want the very best signal there is, everywhere, is to use them all!

All-Network SIM
ParentShield All-Network SIM cards and eSIM attach to multiple UK networks, and use the strongest signal. Simply put – no network provides better coverage because we combine the coverage of networks to protect our valuable users.
SIM-Only Contracts – cancel at any time
Overspending is impossible – these are the prices you pay, and there is no way the user can ever run up a surprise bill.

All-Network Coverage, Same Trusted ParentShield Features!
Ultra Secure – Call Blocking
The strongest blocking capabilities possible. Block absolutely everything and add chosen numbers to an allow-list, or block individual callers’ calls and texts with a single click instantly and without needing to touch the phone.


Unlimited Calls & Texts Home
ParentShield SIM cards have two “Home Numbers” that can be called, or texted, at any time, even if the user has run out of minutes or texts. Children should always be able to call or text home. Home numbers can be Landlines or Mobiles.
If data has run out (Safe Stage 2 or above), a simple button press will add ample more for location apps or instant messaging free of any charge.
Record All Texts
ALL text messages are recorded & stored in an online account for you to review.
Even if texts are deleted from the phone, they stay in your ParentShield Portal for you to check.


Record All Calls
ALL calls are recorded & stored in a secure online portal for you to listen to & download.
Even if you choose not to check recorded calls regularly – most customers don’t – you have peace of mind knowing they’re there. Just in case.
Spending Controls
ALL opportunities for extra spending are permanently blocked. Overspending is impossible!
Premium rate SMS, premium rate phone numbers, charity donations, telephone voting, ‘pay by phone’ subscription services are ALL blocked and will never be available.


Time Controls
Take full control over the times that your child can talk, text or use mobile data.
Set Bedtime and after that time the ParentShield SIM can’t call, text, or use mobile data. The only exceptions are for the emergency ‘Home Numbers’ and Emergency Services.
Budgeting Controls
Turn on our unique Data Budgeting feature to provide a daily data budget so data will always last all month.
Instead of being able to use a whole month’s data allowance in one go, you can spread it out evenly.


Detailed Alerts
Be alerted instantly by text message to YOUR phone should a message to or from your child’s phone contain any concerning words or phrases, or even if your child starts communicating with someone you don’t know.
ParentShield is the UK’s Child Protection network, and to provide maximum coverage, and maximum protection for our valuable users, we offer an incredible all-network SIM that will find the strongest signal and connect to that, wherever you are.
Your ParentShield SIM is a true roaming SIM. It doesn’t rely on one particular network. While our preferred network, because of their superior 4G and 5G technology is Three, we have the ability to provision a SIM onto other UK networks as well. If you are particularly remote, your ParentShield SIM can be specified to roam seamlessly across all available networks. This gives you a coverage that has to be seen to be believed.
For the Technical, our roaming is ‘unsteared’ which means we don’t pin you to one network and then roam if that network drops out. We allow our SIM to do what it’s designed to do, and roam freely onto the networks with the best coverage.
With all mobile networks, there are winners and losers and some areas that struggle. In cases where you can’t get any signal we will always refund the original first month’s subscription.
SIM roams onto the strongest network
Wherever you are, the chances are there is some mobile signal. If you have a phone that can only connect to one of the four networks, then you have a chance of making calls, sending texts, and using data if that one network has signal. We’re all familiar with the situation where your friends have a signal – and you don’t 🙁
ParentShield’s new Roaming SIM is configured to find the strongest signal from any of the networks it’s configured for – if your friends are envious of your network now, don’t be surprised.
Use an Unlocked Phone
To benefit from a roaming SIM you will need a phone that is able to connect to all mobile networks. Until very recently it was common practice for mobile networks, supplying a phone on contract, to lock the phone so it can only work on their network.
Fortunately this practice has been seen as restrictive, and causes a huge headache for customers who want to switch networks.
With an unlocked phone your ParentShield SIM is able to connect to the strongest sim. For help and Information on unlocking, see the network unlocking guide.
