global sim advice please

[infamousurge]

Hi PrepaidGSM members,

I have been going round and round in circles for a week now trying to find a good global sim to suit me... but alas, nothing yet. The whole concept of making/receiving calls abroad seems needlessly complicated... or maybe it's just me?!

Anywho...i went travelling last year to central/south america and bought local sim cards - fantastic option and worked really well. however, during my time there i had a very serious problem (wont go into details) and suffice to say my family were very worried. i agreed to take a global sim on all future travels to ensure i was always contactable to keep their nerves at ease.

i basically need a global sim which operates in all the south america countries (and as many others as possible) and offers free received calls. i dont intend on making outgoing calls/data, just simply for receiving.

i found travelsim - TravelSIM - cheap international calls in 192 countries
but doesnt offer free calls to Brazil, is there anything better? any suggestions/warnings?

many thanks,

infamous
