I have a new-to-me Microsoft Surface 3. I am using a T-Mobile sim that works well in a phone. The speeds in the the Surface are less than .5 mbps on Speedtest compared to 10+mbps in the phone. Does anyone have any idea what is going on? I suspect it is not connecting at 4g. I have done a couple of google searches and found no help. Any help would be appreciated.
Thanks for any help
