I use Multitech MTCBA-G-F2 model based on Wavecom Q2426B since 7 years ago and no problems, they are serial but last year using them with an Startech adapter serial to usb and had no problems with loads about 5-8k a day each, today they are old and hard to find, shure there are newer models and probably only usb model.
I’m using another generic modem usb pool based on Wavecom Q2426B and no problems too, the only issue is that they are aprox 100% to 15% slower than the Multitech but in my case no problem, the average sending speed is 5 to 6 seconds per message.

Right now I am using the Huawei E220 but it becomes unresponsive a few times in a day and it needs to unplugged and plugged back in the USB port to work again. I send and receive thousands of sms messages a day and need something reliable. It looks like many people recommend Wavecom modems, but they are serial and they would be too slow IMO. What modem do you recommend that can handle at least 10 000 messages a day? Also could it be that the Huawei E220 is becoming unresponsive because I'm pushing it's limits (too many sms messages?)
