If your Android phone has been getting / sending multiple copies of the same SMS then you either have a faulty SMS / MMS apk, wrong settings or your phone isn't communicating correctly with your service provider's cell tower. Here are some fixes to consider:
Do a factory reset
Boot into recovery mode
Do a factory reset
Wipe cache partition
Reboot the phone
# Note that factory reset has been reported to be a temporary fix
Remove the SIM
Slot the SIM(s) in another non-Android phone then boot Your Tecno phone without any SIM inside and leave for over 2 hours. Meanwhile, try sending / receiving SMS on the non-Android phone. If you're still having the same issue on the non-Android phone then the fault is from your SIM card; call your service provider.
Replace the SMS / MMS apk
Get a phone of the same model and install a root explorer like ROM toolbox lite . Copy the SMS and MMS apks under System > App and replace the ones on your Tecno phone with them then restart the phone
Delete multiple SMS apps
If you have more than one SMS management app then consider uninstalling all but the stock SMS app
