Hello Dear smsBAG Customers,
During the past 1-2 weeks, you might have noticed increasing NOT_DELIVERED SMS for some of your messages on the MTN Nigeria Network. This is due to a series of new filters that have been updated on the MTN Network.
Unfortunately MTN will not release the key identifiers for this Filters so we are left with guiding our customers to avoid related keywords that represents promos, awards, e.t.c for MTN Network.
Some of the Keywords identified so far includes PROMO, PROMOTION, CONGRATS, AWARD, CONGRATULATIONS, Names of POLITICIANS e.g. Obasanjo, Goodluck Jonathan, e.t.c.
It is advisable that you test you messages if you are sending a bulk message to be sure it will deliver before you blast the message.
On our side, All messages returned as NOT_DELIVERED are still being re-credited into your account if we get a reply from the MTN SMSC Gateway.
We apologize for this inconveniences as we hope this will resolve soon and make sending web2sms more enjoyable again.
