#1 Worst Mistake: Incurring SMS Fees by Messaging Non-Mobile/Bad Numbers

Whenever you send a text message delivery request to your SMS aggregator or carrier, they will perform a carrier lookup to find out which carrier the phone number belongs to. Then the message delivery request is sent to the carrier. If the phone number is a landline or a bad number, your aggregator/carrier will not send the message but, they will still charge you for the message fees.

Carrier failure rates for text messages sent are 15-25% depending on the quality of the data. There are a host of many reasons as to why messages are not delivered but are still being charged:

? landlines, VoIP numbers, fax numbers

? virtual numbers

? carrier blacklisted numbers

? suspended or deactivated numbers

? prepaid cell phones ran out of credits

? carriers that do not accept text messages

If you scrub the phone numbers prior to sending message requests to your carriers, you can save a ton of money. Here is a great super inexpensive solution: https://subscriberverify.com
