I have purchased this sim about 6 times so far. In the UK I have had no problems whatsoever but recently went to the Netherlands. One night in the UK it was working fine but the next night in the Netherlands it wasn't. I contacted Sims4Travel via the email address with the order number and they responded amazingly fast. I emailed them at 18:59 on a Saturday evening and had an answer by 19:28 (one minute less then 1/2 hour). I am very impressed. They suggested the solution which worked fine but also asked for the router I was using. By return email they sent me the electronic version of the instructions in case I had problems with any settings. Simply amazing service. Review: Check twice your details before entering. - Arrived promptly, set up was easy, remember you only get one chance to activate the sim so take time and check twice before you enter any details.

Within half hour my sim was up and running and confirmed by email from sims4travel. 5 star deserved. ### ⭐ Not Working! *by D***H on 19 April 2026* Sim card arrived today, gone through the process on the "sims4travel" website to activate the sim, something that shouldn't be needed as every other provider I have had sims from, just work with no need for emails, id scans, sim card numbers, order numbers, ancient archaeological history of the human race in order to work. The email you receive and the website both say "Activation will take up to 2 hours, more commonly 15 to 30 minutes", the sim card has still not activated after 2.5 hours. I should not have listened to the reviews saying "Worked straight away". I am going to give it till tomorrow morning (Monday) to start working or I will start a refund request with Amazon. **Update** So the sim card was activated on the Monday, however it was in the afternoon/evening when it was activated. There was an excuse of "O2 system issues" but after looking around it would appear that the sim cards don't get activated during a weekend, so that should be mentioned in the advert. The speed though is an issue though, it's atrocious, it's supposed to be 5G but connects only at 4G+ and only get's to 15Mbp/s at it's maximum for a few seconds then drops to less than 2Mbp/s, this is even after a "Sim Refresh". I know the area where I am currently has what is called "Natural Congestion" but in this area O2 are the only company who provides 5G and even within 100 meters of the mast, you still don't get 5G speeds. Overall, I have had to pay for the onsite Wi-Fi to get internet access which is an extortionate price but still cheaper than this sim was! ## Frequently Bought Together - O2 Data Sim Card Preloaded with UNLIMITED 4G/5G Data.
