I recently purchased a Smarty sim card to work with a Tp-link M7350. I am connected ok. I have 3 and a bit to 4 bars on the 4G icon on my router. I have put "mob.asm.net" in APN in dial up settings for my router. I have selected 4g only. I am based in London, and using it inside a red brick house near windows. Network coverage is good.
However, the download and upload speed is 1 Mbps download, and 4 Mbps upload. Very slow! I didn't purchase a "data only" sim, but a sim card that does, calls, text and data. Would this have any influence on performance? Any other ideas why my internet speed might be so slow?
