I do get this connection issue around Bandar Utama. Touch N Go, Parking app inside Touch N Go and Grab Pay didn't work. Strangely WhatsApp works. Safari is slow. I had to turn on Airplane Mode and off to "renew" maxis 4G connection. Then, Touc N Go, Grab Pay and Safari works. It's almost as if there was no 4G connectivity even though my iPhone tells me there's 4G connectivity. Is this issue more prevalent to us because 3G was sunset? Perhaps, previously, our phone will switch to 3G and everything was fine (or, we did not notice anything wrong). Without 3G, this fake 4G appears  :confused: Weird.
