What to do if a phone call does not go through to a TravelSIM device and the caller gets an error message instead?


Some operators have blocked calls to some Estonian numbers, which means that some phones with a subscription to TravelSIM do not connect to the call but will answer:


Call blocked

No number in use

Cannot connect to the selected number


There is a workaround for this:


Create a new contact in your phonebook using the collar share name and replace "+" in front of the phone number by some international carrier code

If not sure which prefix codes are available for your, then check this from your own mobile operator customer service 


Here's an xample and this is from Finland where one of the most widely used international carrier codes is a 990 prefix


Phone number of the TravelSIM card in your device: + 37281xxxxxx
In Tracker App the phone number is shown in targets own settings page as: + 37281xxxxxx
Save this in your phone’s phonebook as 99037281xxxxxx and call to TravelSIM by using this 990 prefix to replace "+"


It must not be replaced in the app for it must remain in original format + 37281xxxxxx 

(otherwise Tracker live service won't be able to use it, if it doesn't use the proper international format for phone number)
