So no issue getting the free line by T-Force via Twitter using my own SIMs I got from A71 phone. My question is I know this comes with unlimited call/text, what about data? should I turn off the data for this line? Can't find information about data for these free lines. TIA.
This line should match every other phone line you have on the plan

So I got a free line yesterday and the rep said I could get the $100 shopcard. But Im reading it wont go through? Can I go back to Costco and ask them to honor it since that was what the rep told me?

Also is the port in a line for $100 dead? So I can port in a number to this free line I just got?

I have 4 lines (2 with 10GB hotspot, 2 with no hotspot). This is my 1st free line so now I have 5 lines. I wonder how T-Mobile decides which lines that it would inherit the data plan. I know I won't get kick back but this seems too good to be true. Initially I thought this is just talk&text with no data. I regret not jumping on this last month.

Do you mind sharing how much are you ending up at for 4a ? Might be enough of wife.. or looking for any deal that is slick for adding a phone with this line
Quote from jaxwithanx View quoted comment :
The current promo says 50% so that would out the cost I pay through monthly installments at $250 roughly. There probably cheaper, better options if your wife isn't a phone/Android geek. But it is pretty much the cheapest you can grab a 5G capable fun right now.
Quote from k000 View quoted comment :
Yes, meant with free line. Does 4a allow a trade in still to make it free?


Will defintely look at it. Thanks both !
The other option I was contemplating (depending on how much you pay for an additional "paid" line) is the OnePlus 8T+5G. This phone is not eligible with the "free" line but it is a "free" phone if you add a "paid" line. My paid line is $10 (+tax) a month so $240 for 24 months

Option#1:
Adding a "free" line I can get 50% OFF Google Pixel 4a 5G ($500-50%off)= $250 over 24 months

Option#2:
Adding a "paid" line I can get a FREE OnePlus 8T+5G, just $10 per month for 24 months ($240)

With November Line on US promotion, I was able to add a free line and trade in an older pixel phone which allow me to get the Pixel 4a5g free, now I need an additional device.

It should be whatever the main line is but you might have to wait and see how it comes up in the account. You can then try and call/message and see if they will put the 10GB hot spot on the line if it isn't on there

Don't waste your time. If you read the OP, it's clearly stated it doesn't stack with the Costco shop card. Now you want to bother a low level employee because he told you something he/she probably doesn't know either. It's the Holidays, let's take it easy. Enjoy your free line and be happy you getting that.

That's a good perspective hadn't thought about just cancelling the paid line after a couple years.

I personally am sticking with the 4a though because I'm at the point only vanilla Google works for me and I'm sick of flashing custom firmware on phones.

Do you pay data for your other lines? If not, contact CS and they should remove that $15/month data fee and they should make it same as your other lines.

Is your free line included free data?
