This new SIM card works on an auto profile selector system. When you land in a new location, please switch on your handset and allow 5-10 minutes for the SIM card to select the correct profile automatically and try to register on the recommended network provider.
Please note that if the SIM card has not connected to the recommended network provider, it is the customer's responsibility to manually connect to the recommended network provider to avoid overcharges.
To view your itemised billing and account history, simply log into your account online at www. worldSIM.com. When the 'My Account' Home Page appears, click on the button that displays your phone number, you will be redirected to a page that displays your itemised billing and account history. To view other numbers associated with your account, return to the My Account Home Page and click on the next number in the same way. If you have any further enquiries, please contact them using the "Contact Us" - Submit Enquiry Form.
To activate data, please create a new Access Point Name with the APN set as 'mobile data' and save the profile as WorldSIM. Please ensure data roaming is enabled. Remember, that every time you change your location, you might have to configure the APN again as above.
If your data SIM card is not working, try to do the following:
Restart your device
Rather than connecting to the network provider or searching for it, create an APN first with 'mobile data' and save it as WorldSIM.
Once you are done with the APN then try searching for the recommended network provider for the country you are roaming in.
Connect to the recommend one.
Check if your internet is working. If not then please contact them on live chat (look in the bottom right-hand corner of the screen).
