I have this idea where i would have multiple cellular sim modules and it will be controlled by a master contoller which would then collates all the incoming text messages from the different number and send it to one master number.
Im looking for the best module for the job. I need a good module that is well supported with libraries or atleast a lot of people in community know how to operate, so i can ask questions and have a higher chance of getting answered
The common ones it would seem are the SIM800 and SIM900. Im leaning on the SIM900 as it is much cheaper the only major difference i can find with it and the SIM800 is bluetooth, which i do not need. Downside to the sim900 is it would seem to be obselete now.
Any recommendations? For know i only need sms, share the modules that youu have used maybe in the future i need a more powerfull module that can do LTE so any suggestions are welcome.
i checked them out, they cost 10x more about 20$ comparerd to the 2$ of the 800. if im spending around that price im might as well get the best. Choosing seems to be a rabbit hole.
Im checking from this store in aliexpress and they have so many models : 7000, 7020, 7080, 7070, 7100, 7500, 7600, 7670. I am also seeing CAT 1 and CAT 4 what are those? (im only familiar with the ethernet cable CAT ratings)
Doing the same searching right now, and so far my best fit since I need voice is A7670E.
If you only need SMS, you can probably use whichever that fit your region as all of them support serial communications + SMS. The more expensive ones support higher data bandwidth.
