I want to send SMS Wap Push messages to US carriers. I thought it would work best to use gateway sofware to a GSM modem. Do I still need a Short Code, if I'm sending it via a Modem with a SIM card obtained through a contract with a US carrier? Do I need to have a Modem and smart cart for each carrier for interop between carriers? (for example, my cingular account to Sprint for example) Please reply | |||

Hi, WAP Push is a problem in the US. The first problem is that I'm not aware of any SMS service providers that can deliver binary SMS messages into CDMA carriers such as Verizon and Sprint. The second problem is GSM modem specific. Basically, our experience has been that Cingular and T-Mobile (the two major GSM carriers that are left after the Cingular/ATTWS merger) do not have binary SMS interoperability between them. So if you send a WAP Push message through a GSM modem which has a SIM card for T-Mobile, it will only get delivered properly to other T-Mobile subscribers ... and Cingular subscribers either receive a garbage message or nothing at all. The scenario is similar if the GSM modem has a Cingular SIM. So, WAP Push in the US is pretty much a headache. Using an SMS service provider instead of a GSM modem can generally get you WAP Push delivery into the GSM operators ... but then you have the problem getting to CDMA operators. We're not aware of any good solutions to these issues. -bn | |||
