In general, there are two important settings for mobile data connections:
1- Data roaming must be ON. Most manufacturers turn data roaming OFF by default to avoid high costs of data use in other countries.
Worldmobile sims are specially made for roaming. Data roaming must be ON.
2- APN Settings (Access Point Name / Access Point Names)
Usually APN is set automatically by the devices. But it sometimes happens that APN is not set correctly. Then you need to set APN.
APN for Worldmobile PRO sim is worldmobile
APN for other products (travelsim, travel esim and m2m sim) is send.ee .
GPS trackers usually have 2G connectivity.
Setting of APN can be done by sending SMS messages to the tracker (see the tracker’s documentation, or search the internet for the tracker brand/model)
The phone number of travelsim and m2m sim is on the card and it started with +372.
The phone number of Worldmobile pro sim starts with 3277. You can find out the number by sending an SMS with the PRO sim to a mobile number, or by sending an email to our info email by mentioning the long number on the sims that starts with 8932.
