Number format notes
International numbers work best when saved in E.164 style, meaning +421 followed by the national significant number. From a mobile phone, that usually lets you tap the saved contact from any country without changing the prefix. From a landline or office phone in Ireland, the manual version is 00 before 421.
If the Slovakia number was written for local use, check whether it includes a domestic trunk prefix. Many countries write landlines with a leading 0 for local calls, but that 0 is normally removed after the country code. North American numbers are different: keep the 3-digit area code and 7-digit subscriber number after country code 1.
Costs can differ between landlines and mobiles because carriers route those calls differently. If a number has moved between providers or uses a special service prefix, the billed rate can differ from a normal city landline. For predictable spend, check the country rate before long calls and confirm whether the number is landline, mobile, or premium.
