Polish number questions, answered.
Can I keep my Polish mobile number when moving abroad?
Yes, if your active +48 mobile number is eligible to transfer. Start before the old line is disconnected and keep it active through verification. Availability depends on the carrier and number type, so check eligibility before cancelling your existing service.
How do I transfer a Polish mobile number?
Apply through the new provider and let it coordinate the old contract. Polish number porting is free. Orange Flex can handle its port in the app after identity verification and plan selection.
How long does Polish mobile number porting take?
UKE says the new service must activate no later than one working day after the old service ends. Identity checks, contract notice, and the agreed transfer date can make the overall order longer.
Will bank verification codes and 2FA texts still arrive abroad?
Your transferred number remains a real +48 mobile number, so supported bank messages, one-time codes, and verification texts can keep arriving in the app. No provider can guarantee delivery from every bank or short-code sender.
Can Google Voice keep a Polish +48 number?
No. Personal Google Voice porting accepts active US mobile numbers only. Polish +48 mobile numbers are not eligible.
Can Orange Flex keep my Polish number abroad?
Orange Flex can retain a +48 number on an active 35 PLN monthly or 350 PLN annual plan. Calls and texts remain tied to its SIM or eSIM, EU roaming is monitored over four months, and non-EU packages can be expensive.
Can I use a local SIM or eSIM with my Polish number?
Yes. Keep My Number uses your internet connection, so you can use a local SIM or eSIM for data while receiving supported calls, texts, and verification codes sent to your +48 number.
