I have read through many of the SIM posts and still need advice. I must know my European number before leaving the US and that number needs to be valid as soon as I land, so I want to buy my SIM in advance. Traveling to Belgium and Austria. I have an unlocked GSM phone.
The other glitch is that it must be good for more than 14 days, which eliminates many of the cards I have found available to order here. (Trip length will be 21-29 days.)
Please do not suggest that I wait until I land and get a SIM and number then. That is not an option due to the circumstances of this trip.
Finally, I have looked into international calling with my carrier (Verizon) but, last time I left the country, despite their repeated assurances that I had an active International plan, I was unable to place or receive calls. (Got a text saying I should have set up an international plan before I left the US -- which I had done!)
Would greatly appreciate suggestions of who to buy from here, or another way to be assigned a number in advance. I know buying in the US can be more expensive.
Thanks, all, so much for your suggestions.
Happy Trails!
