Excellent SIM card!
This SIM card is awesome, the signal's great. Internet's super fast. Got it 'cause my broadband kept flaking out. Seriously, it's as quick as fiber. Easy to activate (activated within a few seconds). Very very happy with the purchase. I use this in Newbury, UK. Signal strength is very good. Other buyers check the Signal quality for your area.

Beware: Not Truly Unlimited
I’ve had to rely on this for two months so far much to my misfortune and no thanks to Virgin Media. For starters, the signal strength is pretty crap; do NOT rely on those sites that supposedly tell you how good a brand’s signal is in your area - I have found every single one to be unreliable. Not only that, but Smarty is technically Three, a company that has much fewer masts than others and therefore much less coverage. Now onto the worst part. The “unlimited” is a load of crap. Both months I’ve used it, it’s started off decent enough, but both times near about several days off from the sub ending the quality drops off drastically. To me that means that there are caps in place whether by speed or GBs, I don’t know. Something definitely runs out before the sub runs out which is simply not good enough for something that claims to be unlimited. As a whole and as a rule at this point, I won’t ever be going for any products that use Three; I had gotten a 200gb data sim for my phone at one point but the signal was so bloody bad I had to cancel it outright as I wasn’t even getting voicemails until days after they were sent. Three are very evidently as scammy and scummy as Virgin Media.
