Activation and Validity

Coverage
Our UK SIM cards work on the O2/Three/Vodafone network, either directly or through their partners. These represent the largest mobile operators in the UK with extensive coverage across England, Scotland, Wales & Northern Ireland. The SIMs provide high speed data on the 4G/5G network.
Using the SIM Card for the first time
- Power off your phone
- Insert your new SIM card
- Power on your phone
- Your phone should connect on a GSM/WCDMA/LTE network.
Please also note, using this SIM card to surf Internet or make calls before reaching UK will significantly reduce the data and voice usage capacity, or even cause the SIM card to stop functioning.
Receiving calls
People anywhere in the world can dial your UK number directly to reach you, for example, +44774132 12345.
Making local calls
To make local calls use the full international format. E.g. to call a UK landline number from any country use (for example) +44 207 222 1234.
Calling an international number when in UK
Dial “+” + country code + phone number. For example, to call India number 022 24216344, dial +91 22 24216344.
Roaming from UK to Europe
These cards permit you to roam from UK to most countries in Europe, however you should have a chargeable activity within the UK ( made a call, sms or used data ) before taking your phone abroad. Local calls and data continue under plan. Local calls mean calls to any of the countries in roaming coverage.

I recently ordered the Unlimited UK SIM Card from TSIM for my trip to the UK, and I couldn’t be more satisfied with their service. From start to finish, the experience was seamless. TSIM delivered the SIM card within 24 hours of my online booking, which was incredibly convenient and fast. Activation was perfectly timed, ensuring I had network access as soon as I landed in the UK.
Throughout my stay, the SIM card worked flawlessly. I experienced great coverage, reliable connectivity, and overall excellent service. It was also a very economical option compared to the higher-priced alternatives I found in both online and offline stores. TSIM’s service was a fantastic choice for staying connected during my travels. Highly recommend!

The TSIM UK SIM’s connectivity was very poor across London. I eventually discarded it and bought a Lebara SIM and used it. I had used TSIM’s SIM in Thailand earlier and it had worked fine. I reached out to TSIM’s support and they tried to help but all their solutions were ineffective. Coverage was very patchy. There was no problem with my phone since the Lebara SIM’s connectivity was smooth.
Services Tsim –
We are sorry the Three UK SIM card did not meet your expectations. Coverage of operators vary by location. We do have options for Lebara SIMs in the drop down. Your feedback is invaluable for deciding which operators to provide, and we will make changes based on complaints such as yours. Thank you for taking the time to record your experiences.

This is absolutely misleading. Once in UK, the money we paid for the sim upfront ran out in no time, and we had to do ‘top-up’s, one after another. We had to pay 40 pounds for this in addition to what we had already paid. I have been using TSim for quite a while, but this is by far the worst experience.
Services Tsim –
We are sorry your activation request was mishandled by our agent. We have processed a refund and also sent you a discount voucher in the hope you will allow us to serve you again. We have used your case to improve our internal procedures. Thank you for taking the trouble to record your experiences and we apologise for the inconvenience.

I purchased sim in Chennai to use in UK. The delivery was on time. The sim worked smoothly in UK. In fact, I used it after returning to India for sometime. It was working better than my Indian simcards!!! Overall the experience was very good.

I have purchased this sim in Mumbai. It comes with complementary gift. This sim got immediately activated after reaching London Airport. So I am able to contact with my relatives. I traveled from south to north UK and west also but there was no any connectivity issues and it is quite economical also. I surely recommend to others also.
Thank you TSIM

The TSIM, was of immense value.
not only were we connected the moment our plane touched ground, but thereafter we were able to connect with our hotel immediately.
the hotel advised us the contact details of the valet who wud be waiting for us.
As we had an immediate business meeting in the next couple of hours we were able to talk to our business colleagues, who got ready for our meeting.
we wanted to drive from London to Lake Districts, so needed to book our car, which we were able to do seamlessly with TSIM.
all in all a great experience TSIM.

I was using TSIM (UK unlimited plan) throughout my UK trip (including England, Scotland & Wales) and it worked flawlessly. I did a few road trips also in the countryside of Scotland and the GPS worked absolutely fine without any issue. I am pleased to recommend TSIM to my fellow travellers and looking forward to taking services from TSIM in the future.
Last but not the least, after placing the order I received my SIM with mobile no on the very next day and it was properly sealed and packed. The moment I landed in the UK, the SIM was activated with 5G frequency. I am definitely a happy customer 🙂
Thanks for the flawless service and my best wishes to team TSIM.
Best,
Lipika
