About this product
Need straightforward mobile service without getting locked into a contract? The SMARTY UNLIMITED 30 Day Pay As You Go SIM Card gives you unlimited data, unlimited calls, and unlimited texts every month on a flexible 1-month plan that you can cancel anytime. It runs on 5G where available, includes unrestricted tethering with no speed caps, and lets you use up to 12GB when roaming in the EU. Setup takes just minutes - pop the SIM into any unlocked device, activate through the SMARTY app or website, pick your plan, and you're connected.

The 3-in-1 SIM works with standard, micro and nano slots, so it fits whichever device you're using. Your plan auto-renews each month unless you decide to cancel, which means you stay connected without having to think about it. If you need to share your connection, tethering is completely unrestricted - use your mobile data on your laptop, tablet or other devices without hitting artificial limits or slowdowns.

Doesn't deliver what it claims
Purchased as a second dimension for a trip to Europe. Claims to offer EU roaming but charges extortionate. SIM now removed

Good if you have a decent network.
I bought this to test the network with an eye to switching from Giffgaff as they do not support Wi-Fi calling on my wife's iPhone 6, although the phone has been proved capable. It didn't work out for me as they wanted me to register and everything (and cough up a tenner!) just to find out. I was still thinking about it until my son's partner said she was on Three and it was poor in our house. Although definitely not rural, we live an an area that is poor with nearly every network. Unfortunately this network was no exception so I will not be bothering. The data you get for the money is impressive - provided you can get a signal.

Hello Soph,
The supplier has advised the following for the SMARTY UNLIMITED 30 Day Pay As You Go SIM Card:
It would work in a router but they suggest that a data only SIM might be better.
They do add though that it will generally work in a 4G or 5G Wi-Fi router, provided:
- The router is unlocked (not restricted to another network).
- The router supports the Three/SMARTY network frequencies used in the UK.
Thank you for using Q&A.
