- In RTR's numbering plan (KEM-V 2009) only 0650–0653, 0655, 0657, 0659–0661, 0663–0699 are “subscriber numbers for public mobile communications services”. RTR's downloadable allocation tables leave out the mobile ranges, and numbers are portable anyway, so the prefix doesn't identify the operator.

Mobile carrier | In RTR's numbering plan (KEM-V 2009) only these ranges are “subscriber numbers for public mobile communications services”. Mind the gaps: 0654, 0656, 0658 and 0662 are not mobile — 0662 is the landline area code for Salzburg. RTR's downloadable allocation tables leave out the mobile ranges, and numbers are portable anyway, so the prefix doesn't identify the operator. |
07xx |
Other | Numbers starting 07 are not mobile: close to two hundred Austrian landline area codes begin with 7 (0732 is Linz, for example). The common claim that Austrian mobiles start with 06 or 07 is wrong. Also 0720 is a “location-independent” range and 0780 is ENUM — neither is mobile. |
Physical SIMs can sign up without issues.

Porting rules in full
Since 1 November 2021, taking your number to another operator has been completely free (under the 2021 Telecommunications Act and the amended number-porting regulation). It takes two steps. First get the “number transfer information” (NÜV-Information): ask in a shop or on the hotline and it must be handed over or emailed within 20 minutes; ask by email or web form and it must arrive by the end of the second working day. It is free, valid for 90 days, and usually needs photo ID. Then file the porting request with the new operator; you agree the switch date with them, and it normally happens overnight, so you barely notice. You can still ask to keep the number for up to a month after the contract ends.
One trap: the legal right to port only applies to a genuine change of operator. RTR's examples are A1 to bob and T-Mobile to S-BUDGET — those are brands of the same company, so they don't count (although most operators let you keep the number anyway).
User share comes from RTR (the Austrian Regulatory Authority for Broadcasting and Telecommunications), as of 2025-12. It shows how widely each operator is used — not how good its signal or service is. Official data →
