@ShelCrow Hi there, I've moved your post over to our Broadband section so other Broadband customers can see it here. I'm guessing you've got a Prepay Broadband SIM card in your Huawei E5576-322, is that correct? If so, roaming is not available on our Prepay Broadband plans so you won't be able to pick up a network in Spain.
Thanks for the reply
