I just tested Call-Off-Load in a US to US call.
Truphone to Truphone---incoming calls free.

I used the STK [SIM Tool Kit] in the phone. NO "+".
[Just tested it again. Did not work with "+".]
Just 1xxxyyyzzzz for both phones.
I think this way [if it works for you] is easier to set up.
1. Put in number you want to receive call at, press OK.
2. Put in number you want to send call to, press OK. Call is set up.

STK call option "Landline callback"
