Topping up UK SIMs in Netherlands
 

Is this possible, and if so, how easy is it for an English speaker? Is it possible to pay cash or use a US credit card to buy the top-up needed to apply the re-load?

UK top ups while abroad
 

Online, Vodafone UK, T-Mobile UK, O2 UK, Tesco and Asda only accept credit/debit cards issued by UK banks.

However, vodafone UK accounts can be topped up over the phone using vouchers bought in these countries:

* Australia - Vodafone
* Austria - Mobikom
* Croatia - Vip
* Egypt - Vodafone
* France - SFR
* Germany - Vodafone
* Greece - Vodafone
* Hungary - Vodafone
* Ireland - Vodafone
* Italy - Vodafone
* Malta - Vodafone
* Netherlands - Vodafone
* New Zealand - Vodafone

Once you’ve bought a voucher, just dial 2345 and select option 6.

I have successfully recharged a British T-Mobile SIM with my German AmEx card after my MasterCards and Visas were all rejected. I presume AmEx don't - or at least didn't - provide the card holder's country of origin to the processing companies. So if you happen to have an AmEx just try it!
