Can I replace the plus sign with 00?
Use + notation in Talkala. On a carrier phone, the international access prefix depends on where you call from and your carrier; it is not always 00. That access prefix replaces the plus sign, not the 1 country-code digits.
How can I call Sint Maarten with Talkala?
