Hi ,
Welcome to the Community from Vodafone.
I will try to say it in english
😛 Yes you can transfer your number to Vodafone, but you have to get first your subscription at Vodafone and then you have to tell them that you want your number from T-Mobile to Vodafone (better is to call Vodafone first 0800-0200056). Vodafone use a Fair Use Policy too, you can see it here:
https://www.vodafone.nl/shop/mobiel/abonnement/redelijk-gebruik.shtml Do you want to use your subscription in the EU? Then you must be able to demonstrate that you have a lasting bond with the Netherlands. There is a lasting bond if you live, work or study here.
But also when you: -lives in the Netherlands but works abroad or vice versa (frontier workers)
-for a number of months 'overwintering' within the EU
Have you used your subscription more abroad in four months than in the Netherlands? Then we will contact you. You will receive an SMS in which we inform you about your consumption abroad. You will then have two weeks to prove your durable bond with the Netherlands and to adjust your internet usage abroad.
See the website and try to translate with google. Here is more information about using in the EU. And i say, it is better to call Vodafone 0800-0200056.
