Mobile prefixes by carrier.
Number portability applies — a prefix only shows the original carrier.
Porting rules in full
Porting is available and free; under the regulator UKE’s rules it must be completed no later than one business day after the start date set in your contract. So the prefixes below only show who originally issued a number. They come from UKE’s official mobile numbering table; only each operator’s main wholly-owned blocks (down to three digits) are listed here — there are also many small four- and five-digit blocks, plus numbers held by smaller operators and MVNOs; see the UKE numbering table for the full range-by-range allocation. An easy pattern to remember: in the 60x, 66x and 69x groups, odd last digits belong to Plus and even ones to T-Mobile.
Network-experience stars are derived from the awards each operator won in the Opensignal report of 2026-05 (data collected Jan 01 - Mar 31, 2026): the most-awarded operator gets 5 stars, the rest proportionally, with a shared award counting as half. They reflect network testing only — not prices or customer service. Test report →
