Very slow 4 and 5G speeds

I've just joined Smarty. Iam getting 5g in my house with 200 mb/s download; I live less than 1/2 a mile away from a Three mast. OFCOM's mobile coverage checker is a great tool to check your area if you were thinking of changing again. In general i've noticed that the number of bars showing on my reception indicator often bears no resemblance to speed of data; 5 bars: sometimes slow, & vice versa. I've noticed that with Vodafone too. Perhaps the number of bars just indicates voice call reception strength. I would stick with it for the month, to see what your overall experience is in different places.  Check your connection settings also. I wish you luck.
