I have a SIM card, bought last May, with about 10E left on it. Not likely to be back to Spain, alas, for a while, and not even Europe for some time. So rather than have it sit around expiring, I'd like to make a small contribution to the web forum that has helped me.
First Full Member in good repute gets it. Besides being free, other advantage is you know the phone# before you get to Spain.
If whoever gets it wants to continue the chain, passing it on to another MadridManniste, that would be nice.
