Global use depends on the phone and your carrier. Most phones on ATT should work in Europe, as should any other GSM-based phone, but the usage rate without an international plan is really expensive. Blackberrys should work overseas but it’s always best to ask and be sure before spending money on one.
Only Verizon’s 4G phones will work overseas and definately ask before buying.
Btw, Verizon’s 4G network sounds to be pretty epic. SIM cards, longer reaching towers, and during initial testing they were seeing 50-100MBit/sec downstream speeds. GG
Oh I f*ckin’ love SIM cards. Every time I get in a country, I get a *edited*ty phone and a card. I feel all Jason Bourne-like 
Even if the blackberry charges you up the wazoo for international calls, they gots wireless & now Skype (plus the whole bbn thing works). As long as I can send emails with attachments, I’ll just stick to the SIM card in a *edited*ty phone for chit chat.

No not every black berry can be used globally. Ask what ones before you buy. I know the tour does but thats all I can attest to. Dealing with e mails on my black berry is very very simple and I usually dont even check them from a pc anymore unless I have to open up something big or send a file out. As far as the fun factor of it well….its non existant but hey black berrys were first made for the business man so yeah what do you expect.
My little sis has the tour & it’s worked for her in China & Tea Town. What’s the limit on the email attachments? The only fun thing I’d expect is music. I’ll be way too busy to play monkey-in-a-glass-ball
