Should you use automatic or manual network selection?

There are two ways of selecting a network. You can either set your handset to use AUTOMATIC Network selection or MANUAL selection. When using automatic selection the handset will look for all networks that it is able to attach to and logs onto the first network it finds. When using manual selection you must manually search through the networks and select a network to attach to. We recommend using automatic network selection. Please refer to your handset manual to check the default settings for your phone.

Setting data on your phone

Please ensure Mobile Data & Data Roaming is enabled on your phone. Setup APN (Access Point Name) manually as follows:

On Android Phones, tap the Menu button  /  Settings / Mobile networks  / Access Point Names / New APN / Set Name &  Respective APN / OK / Save
On iPhone: Tap Settings / General / Network / Cellular Data Network / APN and enter respective APN. Leave username & password blank.  Tap Network

    Great Global Data Simcard, have purchased it multiple previous times. Worked really well in USA, UK, MEXICO.

    • Services Tsim

      Thank you for your kind review and long support.

  2. Nishant (verified owner)

    Took some time to register once I landed but worked very well thereafter. Need to speed up initial registration.

    • Services Tsim

      Thank you for your balanced review.

  3. Padmanabhan (verified owner)

    The TSIM worked fine in Switzerland and Paris. Both calls and Data worked fine. But in USA it gave me only 2G connection. So using data was very difficult. Initially I was using 2 sims in my phone and the TSIM customer care suggested me to remove the non-TSIM from my mobile. Even that did not work. I even tried in a different andorid phone, but I received only 2G connection (Network connected was T-Mobile). Occasionally I received d4G connection when the mobile network connected was Verizon 4G. I tried setting Verizon 4G as the default network in my phone, but that also did not work. My mobile was automatically getting connected to T-Mobile 2G whenever its available.

    • Services Tsim

      We are sorry you did not get 4G speeds in USA and will investigate further why this happened. Thank you for your balanced review and for taking the time to record your experiences.

  4. Vijay (verified owner)

    SIM Won’t worked at all. It’s scam. I got a email that your sim is activated but it was not working. When I called on them to check it. They said that it will work in UK AND US once you land there. But same issue..the number you have called can not accept a call. Sim number is +447463381043. This is happening second time. This is scam. Please don’t buy any sim from them and save your money and frastation.

  5. Niraj

    No accountability in providing service. Typing this in the US stranded with an unactivated tsim. You can easily miss the email asking for docs to be uploaded(assuming that led to my problem), but c’mon … is a phone call too much to ask? I would recommend staying with your local service provider and turning on international roaming for a grand more. You get seamless connectivity once you land abroad.

    Simple change to your UI that can make the customer’s life easier. Ask for travel dates instead of activation date and then actively followup in case activation has not happened by travel date. This is constructive feedback so other customers don’t get stranded after landing abroad.

    • Services Tsim

      It is true your activation could not be processed due to lack of documents. We regret the inconvenience. The amount of communication required for each step is a balancing act since some customers do not want too many reminders and communications. We are however reworking our communication protocol keeping your suggestions in mind. Thank you for taking time to record your experiences.

  6. Bhagvatiprasad Patel (verified owner)

    It was great experience. It’s very cheap in comparison with international roaming.
    You can talk with what’s app.
    It covered more countries then listed.

    • Services Tsim

      Thank you for your kind review.

  7. Abu Huzaifa (verified owner)

    Worked perfectly well. Inserted and everything was ready to use. Data also worked very well. You should also add gulf countries in your world sim card or have a separate option for that.

    • Services Tsim

      Thank you for your kind review and valuable suggestions. We are certainly looking to improve our coverage of gulf countries.

  8. jai (verified owner)

    Good product… Used it in Bulgaria..it worked well..Data speed was also good… Better to go with TSIM rather than Matrix ..

    • Services Tsim

      Thank you for your kind review and recommendation.

    I bought this sim for use in Guatemala and Honduras. I did check with them for the connectivity before departure. The Sim worked in Guatemala but did not work in Honduras.

    • Services Tsim

      We are sorry the SIM did not work for you at Honduras. Thank you for your balanced review.

  10. Vineet (verified owner)

    Worked well in Germany, France & USA. Recommended…!!

    • Services Tsim

      Thank you for your kind review and for specifying the countries in which it worked.

  11. Mona Dhanagare (verified owner)

    We used the card in South Korea, only once for an incoming call. But cannot understand the balance minutes calculations as we had taken plan of 360 minutes and after one call now only 131 minutes are left. The site shows only minutes left and not the balance of data.
    Also, it would be better if we get notifications on used minutes & data consumed to utilise the card accordingly. Thank You.

    • Services Tsim

      You had checked the balance information at the balance check page for Lifetime cards. That page does not show you the balance for Unlimited cards. We are working on a way to provide balance information for unlimited cards too. Thank you for taking the time to review the SIM card.

  12. Deepinder Singh Kalra (verified owner)

    I used this for South Korea, where not a lot of operators work. I compared with other companies and found this the most viable option. The callback option for making calls fails at times, but at least it has a calling option, which a lot of other companies don’t give!

    • Services Tsim

      Thank you for your kind and balanced review, and for specifying the country in which it worked.

  13. Sashank (verified owner)

    I used the Europe SIM in UK, France, Belgium and Netherlands. It worked fine and I did not have any issues. The rs 1500 plan is perfect for a 2 week vacation. I had previously used TSIM when I went to Thailand too.

    Only concern I had was that I was contacted very late to provide the Visa details for the activation of my SIM, literally when I was in the flight. Hence my SIM got activated only one day after I reached Europe. Please contact us well in advance. Otherwise I am very happy with your service.

    • Services Tsim

      We are sorry for the delay in collecting your documents. We will be analysing your case to see how we could do better. Thank you for bringing this to our notice and for your balanced review.

  14. Deepinder Singh (verified owner)

    It was an absolute charm to use the SIM. Worked seamlessly across Italy, Swizz, Amsterdam, Singapore and Australia! Full marks

      Thank you for your kind review and for specifying the countries in which it worked.

  15. SHIVAM BANSAL (verified owner)

    The minutes as provided by the offer were much lesser than mentioned. Whats App Support was very poor. The support team could not provide any details of Balance Minutes & Data. Pre Paid SIM cards can only be useful when Balance Minutes/ Data can be known so that proper utilization can be done. Please update the same or any method/ support for same.

    • Services Tsim

      The minutes available varies as per country. We are sorry the SIM card did not meet your expectations. Thank you for taking the time to review the product.

  16. Satya Nand jha (verified owner)

    I bought this SIM for use in Europe and Americas over 10 day period.
    First 4 days worked well in Europe but next 5 days were a nightmare in Americas. The phone didnt work at all for any calls. Funny thing is they ask you to call back 🙂 when your phone is not working. Eventually after 5 days in the US, it turned out their instructions to use 4G is wrong. so you cant use the phone for 4G in americas, and they didnt think it was important to mention to their customer to switch to 2G in Americas. Poor experience. Eventually they became available to help on whatsApp (over hotel wireless ofcourse).

    • Services Tsim

  17. Firdaus Somjee (verified owner)

    I bought two international cards for use in New Zealand . Both did not work as they do not register on local Networks .
    Waste of money in Pacific region .
    They may work in Europe or USA.
    Don’t take risk . My complaints by mail were of no use . They don’t work period.

    • Services Tsim

      We are sorry we could not resolve your issue in time. We have taken steps to prevent this from happening to other travelers. Thank you for taking the time to write a review.

    One of the Phone Chips did not work during the full duration of the trip.
    Three Chips the Data did not work through out the trip
    One Chip phone and Data worked for part of the trip
    Why take such Chips if they do not work and the team does not solve the problem

    • Services Tsim

      The APN setting needs to be done for each SIM card, which was possibly not correctly done in 3 of the SIM cards. We will be in touch with you to take this further.

  19. Moushumi Parija (verified owner)

    Worked well, quick response to any query, the differential data amounts is a little tough to remember

    The global SIM card worked after complaining in Greece although I could not make a single phone call. In Egypt it was a disaster

    • Services Tsim

      You ran out of credit & Data in Egypt. You get less data in Egypt than in other countries as recorded in the product page. Thank you for your review.
