problem with Swisscom NATEL GPRS
 

Hello,
i ordered a Natel Prepaidcard on ebay some time ago and it worked very well on GPRS roaming. So I ordered 10 more for our company.

Now only the first card goes online in GPRS, all others get a PPP failure (all using the same settings in the same test modem). Is there any trick to activate GPRS? The cards work for voice and SMS so they are active.

thanks for any info,

Chris
