Which SMS platforms in Wuxi accept the free test of SMS interface?

Regular SMS companies will give it a test. But at the same time, the SMS company will get your test number. A few short messages can't test whether the company is formal or not, and how the arrival rate is. But after getting the test number. I'm sure I will receive your test number when I operate. But the batch is hard to say. Bad companies deduct a lot. So don't look for an irregular company. The difference of a penny may not be received by all your numbers. Then you wasted all your investment for a penny. It can't realize the function of notification.
