Sign for 1GB transfer. You'll need to buy your own 3G modem :(
100 Bs.

Sign for 3GB transfer. Same as above

---------------------------
Buy 3G access by using your currently enabled SIMcard:
Send a SMS with "Dia", "Semana" or "Mes" on it, to 4646

"Dia" gives full 1-day internet access account (not accumulative, the 24hrs will run out even if not used)
1-day suscription costs 20 Bs.

"Semana" gives full 1-week internet access (will run out even if not used)
1-week suscription costs 100 Bs.

"Mes" gives full 1-month internet access
It costs 299 Bs.

All the above do NOT have a download limit, however, if you exceed the bought time, you'll be "punished" with a 4 Bs. per MB fee. Not a good at all :)
