T-Mobile offers mandatory a proxy to reduce the size of images. This leads to faster download of websites, but also results in so strange behavior if you use in the same CAR-A-WAN another provider. Why?

T-Mobile translates every html-file and replaces the ULR of the images with a link to the smaller version in their cache. If now the frame if fetched through the vodafone.d-network and the CAR-A-WAN decides due of a network insufficience in the T-Mobile network to re-route the the traffic through the other module, the links to the images are wrong, because the smaller images are only reachable from the T-Mobile-network itself.

The workaround is to use another APN, which is not affected by a mandatory proxy: ca.t-mobile

Important: This APN has to be registered with your SIM card, so please you hotline and ask for a free registration.
