Using only the SMS-function on Huawei E3372 dongle (still in need of wi-fi)

Question

I'm trying to write a python script where I automatically can send text messages. I am achieving this by using a Huawei E3372 dongle which is doing its work so far.

The problem:

Whenever I plug in the dongle, my whole network changes to this dongle. This is a problem because I'm pulling the text message data from an excel sheet that gets downloaded a few minutes before sending the texts out.

The solution I'm hoping for:

Is there any way I can use a wi-fi network and the dongle simultaneously? I know this might be a stretch but the only workaround I'm seeing is to turn off the actual network, which is giving me another problem:

When i use

    C:\Users\x>wmic nic get name, index
Index  Name
0      Microsoft Kernel Debug Network Adapter
1      Intel(R) Dual Band Wireless-AC 8265
2      Intel(R) Ethernet Connection (4) I219-LM
3      Microsoft Wi-Fi Direct Virtual Adapter
4      Microsoft Wi-Fi Direct Virtual Adapter #2
5      WAN Miniport (SSTP)
6      WAN Miniport (IKEv2)
7      WAN Miniport (L2TP)
8      WAN Miniport (PPTP)
9      WAN Miniport (PPPOE)
10     WAN Miniport (IP)
11     WAN Miniport (IPv6)
12     WAN Miniport (Network Monitor)
13     Bluetooth Device (Personal Area Network)
14     Remote NDIS based Internet Sharing Device

14 should be the device, then I use:

wmic path win32_networkadapter where index=14 call enable

I get the message:

    C:\Users\xxx>wmic path win32_networkadapter where index=14 call enable
Executing (\\NB-ACCOUNTMGR\root\cimv2:Win32_NetworkAdapter.DeviceID="14")->enable()
Method execution successful.
Out Parameters:
instance of __PARAMETERS
{
        ReturnValue = 0;
};

Does anyone know why this happens? Even better, is there a fix so I dont have to use all this?
