Infobip is a large international CPaaS platform with global reach. kwtSMS is a Kuwaiti SMS provider that has been running since 2007. Both send SMS. The difference that matters is what happens to your message once it reaches a Kuwaiti network.
Kuwait's mobile operators apply strict rules to commercial SMS. A Sender ID must be pre-registered with the operators, and the traffic has to be bought through a local provider. Messages that arrive from an international route with an unregistered Sender ID are commonly filtered or dropped before they reach the handset.
This is not a criticism of Infobip's platform, which is capable and well engineered. It is a statement about the Kuwaiti route. If your OTPs need to land in Kuwait every time, buy that leg locally. We wrote about the mechanics in why OTPs from international providers fail in Kuwait.

We would rather you pick the right tool than the one we sell. Infobip, or another global CPaaS, is likely a better fit if:
Plenty of our customers do. They route Kuwait and the Gulf through kwtSMS for delivery, and keep an international provider for the rest of the world. Our API is a single JSON endpoint, so adding it as a second route is usually an afternoon of work. See the developer reference.
Do not take our word for delivery. Create a free test account, no documents and no payment, send a message to your own Kuwaiti number, and compare what arrives and how fast. That test takes five minutes and settles the question better than any comparison table.
