SOLVED: MR1100 can't get above 0.5mbit

EDIT: Using a different SIM worked and get expected speeds now. Very weird. All SIMS from same order, but just didn't like that one I guess.

I have an MR1100 I'm running on a T-Mobile tablet biz plan. The MR1100 has magic'd and I created a shell script on it that runs in init.d that sets the TTL:

/etc/init.d # cat ttl.sh
#! /bin/sh
# Setting TTL to 64
iptables -t mangle -p all -I POSTROUTING -o rmnet_data0 -j TTL --ttl-set 64
ip6tables -t mangle -p all -I POSTROUTING -o rmnet_data0 -m hl ! --hl-eq 255 -j HL --hl-set 64
iptables -t mangle -p all -I FORWARD -o rmnet_data0 -j TTL --ttl-set 64
ip6tables -t mangle -p all -I FORWARD -o rmnet_data0 -m hl ! --hl-eq 255 -j HL --hl-set 64

I have the apn set to fast.t-mobile.com and the mode is IP4/IP6. I have no idea what I'm doing wrong, but it connects but I cannot get speeds over about 0.5Mbit. Obviously I'm messing something up somewhere. Any thoughts?

I have checked this SIM in an iPad Pro, gets 200+Mbit

Thanks!
