ParentShield SIM review: worth £9 a month for a child's first phone?
An honest ParentShield SIM review: £9 a month on EE, a whitelist of allowed numbers, call and text logs, quiet hours. Who it suits, who it doesn't.
ParentShield is the SIM Knock ranks first for a child’s first phone. From £9 a month on EE, it’s the only UK SIM built specifically for a child’s phone: you whitelist who can call and text in both directions, you see the call and text logs, and you can set quiet hours. For an 8 to 11 year old on a basic phone, we think that’s worth £3 a month more than Smarty. The trade-offs, below.
What it is, and how we judge it
ParentShield is a child-specific mobile service running on EE’s network. Plans start at £9 a month, rolling monthly with no minimum term. Tariffs run from 250 MB to 5 GB of data and 100 minutes to unlimited, with unlimited texts on most tariffs.
Knock doesn’t lab-test SIMs and we aren’t the network. This review is our editorial reading of ParentShield’s published tariffs and features, set against the other three SIMs in our rankings.
What the controls actually do
Three things, all at SIM level, not on the handset.
The whitelist. You choose which numbers can call or text your child, and which your child can call or text. It works in both directions, a whitelist rather than a blocklist: an unknown cold caller doesn’t ring through, which matters in households worried about cold-call scams aimed at children.
The logs. Call and text activity is visible to the parent; the call log goes to a parent’s email.
Quiet hours. You set times when the SIM goes quiet, so the phone rests overnight without an argument.
Who it’s for
Children aged 8 to 11 on a basic phone. A Nokia 3210 has no apps and no browser, so there are no on-device controls to lean on. Any controls have to sit on the SIM, which is exactly the job ParentShield is built for.
Who it isn’t for
Two groups. Older teenagers, who will rightly object to a parent reading their call and text logs; at that age visibility costs more trust than it buys safety. And anyone avoiding a monthly subscription: ParentShield is a rolling monthly plan, so if a PAYG spending ceiling appeals more, read PAYG vs SIM-only first.
ParentShield vs Smarty, and vs the phone’s own controls
Smarty costs £6 a month on Three, with unlimited minutes and texts and data from 2 GB. No parental controls at all, and that’s the whole trade: the extra £3 buys the whitelist, the logs and the quiet hours, nothing else. If your child is older, or your house rules are doing the job, Smarty is the right answer and we say so. Both links pay Knock an Awin commission, so money doesn’t tilt the advice.
On a smartphone the logic flips. Controls belong on the phone (Apple Screen Time, or a managed handset like Pinwheel), and a plain SIM such as Smarty, or Lebara at £4 on Vodafone, covers the connectivity. ParentShield’s case is strongest exactly where the phone offers nothing.
Keeping the number when you switch
Under Ofcom’s text-to-switch scheme, text PAC to 65075 from the old SIM, free on every UK network. Give the code to ParentShield and they complete the switch within one working day; the PAC stays valid for 30 days. For a new number instead, text STAC to 75075. Our switching kit has the steps.

Common questions
How much does ParentShield cost? From £9 a month, rolling monthly with no minimum term. Tariffs run from 250 MB to 5 GB of data, 100 minutes to unlimited, and unlimited texts on most tariffs.
What network does ParentShield run on? EE. So coverage where you live is EE coverage. Check EE coverage for your postcode before signing up.
Is ParentShield worth £3 more a month than Smarty? If you want the whitelist, the parent-facing logs and quiet hours, yes. Smarty at £6 on Three has no parental controls. If house rules and a basic phone already cover it, Smarty is the right answer.
Can my child keep their number when switching to ParentShield? Yes. Under Ofcom’s text-to-switch scheme, text PAC to 65075 from the old SIM, free on every UK network. Give the code to ParentShield within its 30-day validity and the switch completes within one working day.
