Performed a comparison test (see picture below) using a VPN server in Bangkok while actually being 'in the sticks' in Issan at approximately 40 km distance of Laos. Btw. the VPN server of Laos of ExpressVPN happens to be located in Khon Kaen. Strangely, speedtest outcomes show that network wise I'm closer located to Bangkok than Khon Kaen while being physically more close to Khon Kaen. Unless, of course, Laos has also a place named Khon Kaen, which I was not able to find yet, in Laos.
Please don't get upset by the numbers I found. I do not have the intention to startup a speedcontest. In relation to redONE following notions apply:
a mobile virtual network operator (MVNO) is a wireless communications services provider that does not own the wireless network infrastructure over which it provides services to its customers. An MVNO enters into a business agreement with a mobile network operator (MNO) to obtain bulk access to network services at wholesale rates, then sets retail prices independently. Due to less overhead being more cheap. That's a well known fact. Hardware of Thailand MNOs and its speeds have already been discussed in this thread. However, generally, download speeds of a MVNO using a MNO are always lower or by exception at its best equal to the maximum speeds available of the network of the MNO applied In this case probably TOTs 3G and 4G. Thus far, personally, for my usage, regarding redONE, I do have no complaints yet here 'in the stcks' in Issan quite close to Laos. Coverage isn't a problem for me. Luckily for me those problems seem to belong to the past when we were forced to use large antennas here on our houses. Experienced no problem in capital city and province Sakon Nakhon and no problems in Udon Thani and no problems in-between. Number of towers of MNOs have increased rapidly during the last 10 years.
