About this product
Need plenty of data without tying yourself to a contract? The SMARTY 100GB 30 Day Pay As You Go SIM Card gives you 100GB of data, unlimited calls, and unlimited texts for £12 each month on a flexible rolling plan. There's no credit check to worry about, no annual price hikes, and you can cancel whenever it suits you. The SIM fits any unlocked mobile - it's a 3-in-1 format that works as standard, micro or nano - so just pop it in, activate through the Smarty app or their website, and pick your plan.
You get unrestricted tethering without speed caps, which means you can share your connection across laptops and tablets as much as you need. The plan includes 5G data where it's available, and if you're travelling in the EU you can use up to 12GB without extra charges. Your plan renews automatically each month unless you cancel, so you stay connected without having to remember top-ups.

Customers Say
Smarty SIM offers good value, flexible plans, and decent coverage in many areas. Setup can be tricky, and packaging/activation info is sometimes confusing. Mixed experiences with signal and customer service.

Very Confusing
Although the online stock shows this as a 200Gb in a yellow sleeve. The packaging has changed which is now green, with no mention of the Sims capacity. In reality its a blank Sim and when you activate the Sim online you can load it up with whatever capacity you like Even the Sales Assistant at the store had no explanation

Good deal, easy to use
Very good deal, easy to use app to monitor usage and add more data if need be. I use the sim in a TP Link router and it does occassionally drop out but mostly it's fine. (Coverage from Smarty is rated as excellent in my area).

Hi Simon,
SMARTY 200GB 30 Day Pay As You Go SIM Card
Yes this fits any unlocked device.
Thanks for using Q and A.
Hello Skinny,
The supplier has advised the following for the SMARTY 200GB 30 Day Pay As You Go SIM Card:
“ Yes, you can use the SMARTY 200GB 30 Day Pay As You Go SIM Card in a mobile router while on holiday in the UK — as long as the router is unlocked (not locked to another network) and supports UK frequencies.
SMARTY operates on the Three UK network and allows data tethering (hotspot use), which means it can be used in mobile broadband devices such as:
MiFi/mobile Wi-Fi hotspots
4G/5G routers
USB dongles with SIM slots
Things to check before using:
Unlocked device: Your router must be unlocked to all networks or compatible with Three UK.
Network compatibility: Make sure your router supports 3G/4G/5G bands used by Three UK (primarily Band 3 [1800 MHz] and Band 20 [800 MHz] for 4G).
Fair Usage Policy: While 200GB is a large allowance, very high usage (e.g., continuous streaming or downloading) could raise flags. SMARTY doesn’t throttle speeds but monitors for unusual patterns.
Extras:
There’s no credit check or contract.
You can top up or renew after 30 days if needed. ”
Thanks for using Q & A.
Hello Shez,

Hello Richard,
The supplier has advised the following for the SMARTY 120GB 30 Day Pay As You Go SIM Card:
Once you’ve purchased the SIM, you’d then need to go to the SMARTY website to activate it there. It’s not pre-activated, nor is it automatically activated upon purchase. Once the activation process is complete the SIM will be working.
Thank you for using Q&A.
Hello Smiler25,
After checking with the supplier, I can confirm this SMARTY 120GB 30 Day Pay As You Go SIM Card if not top-up at the end of your month's plan and you choose not to renew for another month your plan will end. This means that you won't be able to make calls, send texts, or use data until you renew your account.
If your account is inactive for 220 days, your account will automatically terminate itself.
Thank you for using Q&A
