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.

It works well in certain places, but not all of them. But without a doubt, it is too helpful for a crisis.
Services Tsim –
Thank you for your balanced review.
Gaurav (verified owner) –
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.

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.

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.

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.

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.

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.

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 owner) –
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.

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.

I purchased this UK SIM with unlimited calls and 5 GB data limit for Rs. 1,989/- on 16 May 19. It was delivered to me with some goodies on 18 May 19. Got the sim card activated on 20 May 19. Unfortunately due to the problem of my handset Lenovo K6 Note, the sim card did not wok on the day of arrival in London, UK. I did some research on the internet and got the problem rectified and found the sim card working brilliantly. 98% of the times it gave me 4G speed. and good network with vodafone.
However, the sim started asking for recharge from June 07 June, that is approx 17 days after the sim was activated. The whatsapp customer help number provided was unable to give me a reason for the same. I continued to chat with customer support however they could not resolve the issue until 11 June 19. On 11 June 19 I called up the Lebara local customer support number and they informed me that the plan given to me was not unlimited and it had a cap of 5 GB data and 1000 international +Unlimited UK local calls +1000 UK sms called ALL in 4 (4G) Plan which was locally available for a fee of 15 Pounds.
The Lebara customer support informed me that I should have selected the ALL in 6 (4G) plan by paying Rs. 2,489/- for the all unlimited features for one month. This plan is available locally in UK for 20 Pounds. Hence the plan offered for Rs. 1,989/- is not an unlimited plan and calls to India will stop once you finish your 1000 minutes. SO please do not select this plan if you want unlimited india calls option.
Further the Lebara Customer care was supportive enough and they gave me a discount of 5 pounds and allowed me an unlimited india calls recharge option by paying only 15 pounds which otherwise would have cost me 20 pounds.
I had a long chat with the TSIM Customer Support and informed them about these details. Unfortunately they have still advertised the Rs. 1,989/- plan as unlimited india calls option which is completely wrong. Please purchase Rs. 2,489/- plan if you want all unlimited calls option.
The service provided by the sim otherwise was excellent.

Services Tsim –
We are sorry for the inaccurate information provided to you. The operator modified its plans and gave us very short notice of change, due to which for a short while some customers were informed of the earlier deal but actually got the newer plan. We have updated our web site to reflect the changes. Thank you for taking the time to record your experiences. We apologise for the inconvenience.
Madhusudan Saha (verified owner) –
Recently used UK SIM in London, Western parts of UK (Bath, Bournemouth, Oxford & Lake District). Reception was poor, mostly 3G, sometimes E, (never 4G). Calling Home was okay, but local in UK was erroneous. Messages received from Libara to top up, but since I purchased an unlimited one for Rs 2489/- I ignored the messages. Overall experience is good, but not good enough for Google Map Navigation.
Services Tsim –
We are sorry that you did not get 4G coverage. We have not yet been told by the operator why your phone was unable to latch on to the 4G frequencies. We apologise for the inconvenience.
Anuradha (verified owner) –
Used it in Scotland last month without any problems
Again , as earlier, data promised was 4g but network received all through was only 3G.
Services Tsim –
Thank you for your feedback. In some areas you get 3G that works close to the speed of 4G. We will however investigate why you had 3G throughout, since the operator advertises 99% coverage on 4G, and uses Vodafone UK’s network.
John Devasahayam (verified owner) –
I purchased two UK SIM Cards for a trip to UK. Everything worked like a charm EXCEPT the 10GB data worked only on 3G THRU-OUT THE TRIP. This is contradictory to the description of the product which clearly states ‘One month SIM card gives you 10GB of Data at 4G speed.’ As a result purchasing the 10GB Data was a complete waste as I was unable to use it effectively.
Services Tsim –
We apologise for the trouble you had with the 10GB card and thank you for bringing this to our notice. We are in touch with the supplier to find out why this has happened.

Used for 2 weeks in UK and Ireland. Worked very smoothly with no problems at all. Only thing to remember that when you go out of UK to any other country in Europe, change the data settings as per the brochure supplied with the SIM.
Services Tsim –
Thank you for your kind words and tip for our customers.
Anuradha (verified owner) –
Used this sim last month in London. No probs in activation, happened automatically.
Unlike matrix which was always a problem to activate.
Data though promised 4g but I got only 3G data despite having a 4G phone.
Nonetheless there was no problem at all in calls or in accessing the net even on 3G.
Admin may kindly coordinate amongst their teams to ensure that the customer doesnt get flooded with document upload reminder mails despite having done so already.
Services Tsim –
Thank you for your review, and for pointing out the excessive email reminders. We apologise and are working to put together a mechanism to stop them as soon as documents are verified.

Seamless transition. Very easily connected. Yes it connected using 3g as my phone did not support 4g services in UK, but 3g speeds more than enough, and very consistent.
Services Tsim –
Thank you for your kind review.
Bhavesh Agarwal (verified owner) –
Undoubtedly the most economical option as compared to other famous vendors like Matrix. And it gave me enough speed while in London, the only glitch was it catched all 3G network instead of 4G, but anyway, I didn’t feel much problem with 3G as well. Just ensure that you active (insert the sim) after entering UK (when it enters it’s local network).
Services Tsim –
Thank you for your kind words. Your phone model was not fully compatible with 4G frequencies in UK, hence it may have switched to 3G. Our apologies.

Purchasing the tsim was hassle free. Reached me on time by courier. I was informed about about the activation of the SIM prior to my trip to London. The sim started working immediately after landing Heathrow. Call quality was good. Data was mostly 4G. Only issue was continuous email reminders from server to upload documents even after customer service confirmed receipt of all documents. I would recommend the purchase as a very good option. Got a metal card box as a gift too. Thanks tsim ..
Services Tsim –
Thank you for your kind words and feedback. We will certainly check why repeated email reminders come to you.

PLEASE DONT BUY TSIM. ITS waste of money.. I went to UK with their sim, DATA is only 3g and not 4g as promised .. free minutes to india just get over in 50 calls wherein they promise 500 mins…. customer service is waste and you get lot of local sim for better deal. Data is also very bad. Basically after complaint also till now its 20 days they didnt take any action

The SIM at UK worked like a charm. The call quality to India was Good. People who answer the phones were able to provide me all relevant info and very helpful. They also called me to remind before the travel and ensure everything was fine.
The only problem was this: I was told that the SIM uses Vodafone at UK and hence wherever Vodafone coverage is there, I will get the same — including 3G/4G. Well, that was not true. The SIM uses Lebara network (which may piggy-back on Vodafone, I am not sure). And I ONLY got 3G, and I did NOT get 4G working at all.
Services Tsim –
We are investigating why you did not get 4G. Thank you for your kind words and balanced review.

Thank you for your kind words and review. As per the information from the operator, up to 6.5GB data is available when you take the SIM from UK to Europe. We are sorry you were not able to use Data in Europe, and we will once again confirm this with the operator.
YOGESH JOSHI (verified owner) –
I have been using TSIM since the last 5 years. Never had any issue in any country but this time around there was one constant issue every 3rd day. Whenever i tried to call from the sim, it gave me an automated message that THE BALANCE HAS BEEN USED UP or something like that whereas my plan was 10 GB + UNLIMITED DATA. It was very irritating as i was totally dependent on their service during my stay in london.
Services Tsim –
We are in touch with our operator for the reason why you had this issue. As this was a new product, we have had some teething problems. We appeal to you to continue using our services. We will be in touch with you for further action.
