Yes, bonus codes work I add them to my TMFL LG800G all the time. If a code is good for 100 minutes on a 200 minute card you only get the 100 bonus minutes for the bonus code and then 600 for the 200 which triples for a total of 700 minutes. The TMFL life only applies to PURCHASED minutes and those bonus minutes are not considered PURCHASED minutes. Hope that helps.
I'm guessing the folks who say you can't use them probably tried to use an invalid code on their phone (where you never get any feedback) and when it failed just assumed it was a limitation with their new TMFL phones, boy are they missing out on free minutes. Just my guess on why they got that impression.
My LG 420G phone was running low, and I was interested in a TMFL phone. I bought the LG800g from an ebay store (shopcellphonedeals) I think it was called. The phone was sold as a package deal with a 400 minute/1 year airtime card.
I first went online to transfer phones and phone minutes. It went off without a hitch. I then added the 400minute/1year card with a 300minute bonus code that I found online. It worked. 1500 minutes was the net result.
I think that the people who say that the bonus codes don't work for TMFL phones do not know how to check the codes before committing.
