http://forum.lowyat.net/ Sat, 20 Jun 2026 20:19:58 +0800 FeedCreator 1.7.2 http://forum.lowyat.net/topic/5345613 I&#39;m using Yes 5G &#39;wireless fibre&#39; (which genius came up with this name?). So far so good, I&#39;m actually impressed with getting as advertised speeds, but I&#39;m frustrated with not being able to tinker with the modem.<br /><br />Has anyone tried bypassing/replacing the firmware? Or using another 5G cellular modem?<br /><br />I&#39;m interested to find out if the sim is locked to the modem (is there such a thing? I know phones can be carrier locked) and if the speed cap is on the sim card or on the device itself.<br /><br />The only thing I&#39;ve been able to find out is that the modem uses a Quectel RG500Q-EU chip. I can&#39;t seem to reverse trace the manufacturer as some spec listings seem different.<br /><br />Thanks in advance. tiadanama Networks and Broadband Sun, 08 Jan 2023 09:22:29 +0800
