WCIF: International calling card with internet access?

Canceling local cellphone service soon, I was going to rely on Starbucks for internet access, but don’t they send a SMS to your phone for authentication? So that won’t work.
So I guess I need a calling card? Or one of you sophisticated nomads tell me what’s good. Thanks in advance.

What you need is a SIM card. You can get a pre-paid monthly SIM card from any of the major telecoms.

Thanks.
