Reminder that you have to stay on the dark star network or they will charge you for the 2 other lines ~45 days later.

Do these get activated immediately or can you wait to activate it?

The issue is that this price is only valid for one year.

For the second year you will have to pay $930 (390+270+270) for the three lines.

I would have jumped on it if this price would roll into future years as we have excellent AT&T signal around us.

As already called out, they are super deceptive with the line "port-in". You will get charged if you use anything more than AT&T's crappy network.

you can always port out the free flex lines including your master line for other low cost plan within US Mobile or from other carriers. The market is ultra competitive where every MVNO is fighting for a share

Its not deceptive. They called out explicitly in the deal section that it has to be in the Dark star network. Whether you are ok with it or not is your call based on the AT&T reception around you. You can also stay out of dark star for 36 days in the one year period without attracting the additional fee, but to the most part, this is to attract customers to increase their AT&T base.

But if one does not want to port out at the end of one year, isn't it better to start with a deal like what they had last week for around $200+ (without free lines)? I mean if the plan starts cheaper in the beginning and the price rolls to future years, you will save more in the long run.

Agreed that one wouldn't want to go through the hassle of moving away from network to network. But if you look at the flip side, you aren't getting locked with big carriers like ATT verizon or Tmobile, which always lures customers with free offers and end up charging per line $40 or $50. USMobile natively has annual plans cheaper which would cost approximately around $250 for 12 months. So if you decide to convert your free flex lines a year later, you do have viable options and not really looking at $50 or $60 monthly rates. With this promotion, if you do the calculation, you are paying $11.25 per month per line assuming the 2nd line is used and $7.5 per month per line assuming all three lines are utilized, which is a damn good monthly rate from a decent MVNO. The parent plan also has true unlimited data and 2 free flex plans comes with 10gb data per line per month, which you wont be able to find for a 12 months period. YMMV

I agree with you. The price for the first year is amazing. I am still thinking and evaluating options. Currently have the AT&T annual prepaid and pay around $20 per month. The second year of this promo will be around $25 per month per line. That's why I am not ready yet to pull the trigger. Thank you for your detailed responeses.

You mean like pretty much every other mobile plan deal, it doesn't last forever?
Sure some other promotions last longer, but a if you don't want to keep switching, US Mobile seems to be good value for non promotional pricing

I actually use att with a discount but after taxes and fees I'm paying around $23 per line. At least with us mobile taxes and fees are included.

I don't understand this part. Does it mean that if I have to port in, I have to use Dark Star? if I want new number, I can use the other two networks?
