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.

    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.

    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).

    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.

    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.

    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.
