T-Mobile has a new promotion going on for Family Talk $5 add-a-line going on right now. This promotion will reduce the add-a-line price on Even More plans from $10 to $5. Yes you will have to sign a 2 year contracts on all the new lines opened on the account. If you are going to try and take advantage of this promotion, and you are already an existing customer, you will have to migrate all additional lines to the promotion price, and then agree to contracts for 2 years on all the lines. By acting on this promotion there will be no effect on upgrade eligibility, and this is because upgrades are tenured and not promotional based. One of the exclusions of this promotion is, You CANNOT have both promotional and non-promotional add-a-line pricing. The current pricing on the Even More plans are $10 add-a-lines, and will remain active for existing customers who want to add more lines and don't want to extend their current contracts on their lines. Yes this is one hell of a deal, and Yes T-Mobile usually offers great promotions. I would like to see how this pays off for the wireless carrier, because you know if it didn't, there would be no promotion. Will you be adding a line? [Via TmoNews]
