Activation and Validity
You need to specify an activation date for these cards. No activation on Sundays. Your validity period begins when the card is activated, due to which we suggest to activate only the day before you travel.
The SIMs will be valid for 30 days from the date of activation.
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.

Excellent service. Highly recommended. The only thing is, my Name, DOB, etc were not updated in 3’s records when I logged in to the 3 app.
Service wise I did not face any difficulty. I came to know about my number in India itself in advance.
Thanks a lot

Not suitable for senior citizen as they are unable to use internet. Even though they received the apn settings after 10 days, applied the apn settings still the Internet is not working at all. Waste of money on SIM card received. Earlier we have purchased Lyca SIM card that SIM card working great.
Services Tsim –
We are sorry we couldn’t get the SIM card Data to work for you. Normally the settings are automatic. We ap;ogise for the inconvenience.

It is reasonable Priced, IF WORKS.
Two Stage Dialled Calls were not clear. This situation was faced even in past, Problem continues.
Data Offered was 50GB. To Track the usage we were advised to download and use 3 app. As per that , till 12th day of trip , Dat Used was less than 15GB and on 13th Day, Data Stopped working. Were forced to pay much more and buy a Local SIM and use it. This was frustrating experience.
I believe, IF T-SIM can take care of such abrupt stopping of SIM , it would be worth.
Services Tsim –
We are sorry the SIM card did not work for the full length of your stay. We have been in touch with the backend operators for this issue, but have not got a satisfactory response from them. We advise customers to get in touch with our helpdesk during the trip in such situations. Thank you for taking the time to record your experiences.
K Bharucha (Verified user) –
UK sim (Three UK) worked very well all England giving 5G/4G data most of the time. Activation was also done on time and mobile number was informed by email. Also got a prompt email response to my query during usage period. Had taken a 50GB pack… However a smaller pack would have been adequate.
Well worth the cost.. And comfort of having an active sim as soon as you land abroad.
Services Tsim –
Thank you for your kind review and for pointing out the benefits of the card.
JS (Verified user) –
Did not work. They provided a Lebara sim which only allowed 50 MB of data instead of the promised 2 GB and then was requiring me to make a purchase. Free wifi in coffee shops, restaurants, my hotel, and the tube is what kept me connected. Never going to buy from them. Was a total waste of money.
Services Tsim –
We are sorry the activation could not be processed in time. Lebara did finally activate the plan, but it was too late for your trip. We have processed a refund for you. We are also sending you a coupon towards future purchases in case you would like to give us another chance. Thank you for taking the time to record your experience.

It works well in certain places, but not all of them. But without a doubt, it is too helpful for a crisis.
Services Tsim –

Gaurav (Verified user) –
It worked very well as described.
I wish the telephone no is shared in advance and not on the last day of activation, as in the past.
Services Tsim –
Thank you for your kind review and suggestion. We will certainly work toward sending the number earlier if possible. However some operators generate the number on activation.

Parag Wakankar –
Data stopped working after couple of weeks and i had to resort to my india roaming number
Services Tsim –
Your 15GB Data ran out after 3 weeks due to which your data stopped working while the calls were still functioning. For long stays we suggest higher amounts of Data package. Thank you for recording your experience.
Arundhati Sarkar (Verified user) –
Smooth experience, absolutely no issues. Pro tip: download the Lebara app once you are in the UK to keep track of the minutes 🙂 Happy travels.

Hemant –
The sim was activated, data pack was not charged by the T sim. I was not able to use the sim initially for 1 day after landing which should not have been the case.
Services Tsim –
If the SIM card is not installed in the phone on the day of activation, then the plan does not get installed on the phone even though the SIM card is activated. It then gets activated with a delay on the next day. We are sorry for the inconvenience and have used your case to inform our clients better. Thank you for taking the time to record your experiences.
Santosh Dorge (Verified user) –
TSIM was delivered to my location in Pune in 2 days after I placed order. After reaching to London, I put in TSIM SIM card in phone, and it started working. It was helpful in coordinating with taxi service and other people in the group.
I recommend buying TSIM in India itself, it saves time and helps at airport and when travelling within UK.
Services Tsim –
Thank you for your kind words and recommendation.
Ram Mohan (Verified user) –
I had bought this UK SIM for my daughter who travelled to the UK for the first time for studies. The service was very prompt and I got the UK SIM delivered the next day. The chat service as well as phone response was quite quick and they were able to resolve all my queries. The SIM also worked on landing in UK as promised and that was very convenient in the strange land that my daughter was travelling to. We also recently recharged the SIM on expiry of one month, which was cool.
Services Tsim –
Thank you for your kind and detailed review.

Quick delivery of the unlimited SIM card. Initially, I was not able to call UK numbers when I was in London and complained to the customer service by email. The customer service person called the same day and tested my sim. It was clarified that, one can call UK numbers by adding a 0 before the UK number and it worked fine.. I could male calls to India without any problem. Great service.
Services Tsim –
Thank you for your kind words and review.

It doesn’t work in an international phone
Services Tsim –
Some phones are locked to particular operators. We are glad we could get the SIM working on another phone. Thank you for taking the time to write about your experiences.
afrozvnit (Verified user) –
I had purchased and used the UK unlimited SIM with 5GB data for my trip of 2 weeks in Sept19. This is the second time I’m using TSIM, used it in US before.
The data coverage was my primary need as i was driving in Scotland and Ireland. Had great 4g or 3g coverage in most areas including the National parks. Voice calls were great too. Had access to free voice calls to India while in the UK, and just 4g data nd local calls while in Ireland. The 4G data access was great everywhere.
Would highly recommend TSIM for UK. My experience was great and if data access is your need , just get the 5G variant, it worked like a charm without having to worry about the data limit.
Services Tsim –
Thank you for your detailed review and for confirming the areas in which it worked.
RAVI SHANKAR (Verified user) –

Herchel –
Everything was fine. Network availability was satisfactory.
The only problem I’d say was with 4G.
NEVER during my entire trip did I receive 4G.
Having told customer support on whatsapp, and after trying out what they suggested, STILL i couldn’t get 4G.
And not just at one place, many different parts of UK.
Apart from that the sim worked just fine.
Services Tsim –
We are sorry you could not get 4G on your trip. We are in touch with the operator about this issue. Thank you for your balanced review.
