General Discussion / Re: IPv6 Subnetting and routing from a /48 tunnelbroker network

no you cant custom the subnet prefix that he provided to you
according to https://www.22decembre.eu/2016/05/28/openbsd-ipv6-router-en/
and
As a reference see https://forum.openwrt.org/viewtopic.php?pid=248046#p248046
what he tunnel provides is a non prefix delegation subnet, say if you add an arbitrary value in it, you will encounter slow speed no route-able subnet. its differ from whom provided a native ipv6 subnet that can delegate prefix through DHCPv6-PD.
and try to distinguish
2001:xxx:x:xxx::1/64 with 2001:xxx:x:xxx:1:1/64 if you ownly ra the later subnet its not he tunnel who routed default to you.

A slice of reflexion
You have to, sort of, copy your configuration/topology from ipv4 to ipv6.
HE will give you automatically a /48. If you read my article about ipv6, so you know that your network is of minimal size: you cannot have sub-nets in it. If you have several sub-nets in ipv4 (Ethernet and Wifi separated), then you will have to do the same with ipv6. HE will give you a /48 if the server you registered your tunnel on has enough place while you request it.

Nothing wrong on your side, however your ISP / LTE-carrier must provide you with a delegated prefix for your clients which it doesn't at the moment. You cannot just use an arbitrary value in ip6prefix since it must be routed to you.
