Re: Cellphone connection - faster? Or other?

hi!

Use a UMTS / 3G internet service and openvpn
You might need a server with a real IP since all the providers in  
Germany I have been testing use a NAT to hide you from outside.

O2 and Fonic block SIP but they do have also interesting dayflats.
Note that on the Fonic dayflat you are limited to GPRS if you are over  
1 GB per 24h.
On the O2 monthly packs you are limited to GPRS if you are over 5 GB  
per month.

If you use a USB surf stick make sure you use an external antenna.  
This will make your ping times and packet loss rate much better.

Google a bit and you will find a posting from me how to use a Huawei  
G3 device on NetBSD 5.
