While it is possible to use a GSM modem, there are many disadvantages of doing so. Here’s a quick list:
• Branding – You cannot mask your Sender-ID. Thus, recipient will see your number as the sender. Using flexiSMS, they will see the SMS from, say "FlexiSMS" instead of "+6592778777".
• Features – Certain features like auto-unsubscribe, campaign-based reports may not be available. FlexiSMS is campaign-based and includes auto-unsubscribe feature on top of campaign-based reports and analytics. There are many other features as well which FlexiSMS provides and are unavailable on GSM-modem based software.
• Sending Speed – Sending via GSM modem can be as slow as 1 SMS every 10 seconds. Using FlexiSMS, you can send up to 10 SMS/second.
• Contract – You need to purchase lengthy mobile contracts for the SIM chip. FlexiSMS is affordable and the minimal contract is 30 days.
• Setup Cost – You require initial costs like PC, GSM modem and software. FlexiSMS is simple, you pay for what you use.
