Listed lengths are possible number formats, not proof that a number is assigned or reachable. These instructions cover ordinary mobile and landline numbers. Short codes, emergency numbers and special services use separate numbering rules.
Common questions
Related questions
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 378 country-code digits.
How can I call San Marino with Talkala?
Open the Talkala phone, enter the number and create an account when you're ready to call. You can prepare your call before signing up, and the person answering doesn't need Talkala.
What does it cost to call San Marino?
Talkala currently lists calls to San Marino from $0.62/min for landlines and $1.02/min for mobiles. These are starting rates in Talkala's default public price list. A number's carrier or prefix can change the final rate, which is confirmed before calling. Prices use the default United States caller ID, not your physical location.
When does the free first minute apply?
Eligible accounts with no available credit and no completed paid top-up may receive one free call of up to 60 seconds. The final rate for that call must be $0.99/min or less. Account and destination eligibility are checked before calling. See all free-minute conditions.
