One credit
need not always mean one message. Gateways that show better messages/
credit ratio may have higher price for each credit.
Identify the countries you want to send messages to. Not all gateways serve
all countries.
Check the reliability of the network. If you can, send a test message from the
gateway to determine the delay in delivery.
How many messages will you be sending? There are volume discounts.
Charges also vary according to the destination country and mobile network.
How many will you be sending where?
Check out hidden costs. Set up costs or taxes may be hidden.
Some gateways will also have minimum purchase commitments. Factor this
in when you do your estimates.
Check the validity of the package you buy. You don't want it to
expire unused!
What are the different ways to connect to the gateway? Most support HTTP
access. If you require SMPP, XML or any other, check right at the start.

You should also check the level and type of support available. Are the APIs
well documented? Can you find enough examples on the provider's site as
well as on other sources? (Try Googling a bit!)
Check the type of reports and stats you will have.
