Hi Bryce,

If I have two GPRS modems, both containing SIMs for the same operator, how do I keep the connections separate when performing simultaneous operations?

NowSMS uses Windows Dialup Networking to create a GPRS connection. You also create a routing table entry to direct all traffic to the WAP Gateway via that connection. However, if I have both devices connected at the same time
- and thus two routing entries for the same WAP Gateway - could Modem A's traffic conceivably be routed through the connection created by Modem B or vice-versa?

NowSMS handles this, although you may see some reduced throughput if both modems are sending simultaneously.

We also recommend that you use a traditional WAP/WSP connection instead of a WAP2/HTTP connection. (WAP/WSP is used by default, WAP2/HTTP is only used if the "WAP Gateway IP Address" field is prefixed with "http://".)
