T420 wwan with straight talk?

Anyone have any idea if I could use a straight talk $55/10gB phone card in my Lenovo? Was about to order a wwan card off ebay for $10, and pay for a second cell phone service, I'm running my 10gB limit down too fast tethering. I've been tethering through straight talk for around 4-5 years, never had a issue, but I've never used a wwan card, so not sure how that works.

I'd just keep tethering and use 2 phones, but I don't want to carry around 2 phones half the money so I can keep my main phone around me all the time lol.... Would rather just have a plan for my laptop and one for my phone

edit: I ordered the card

edit 2: well still haven't received my WWAN card yet, but my data was gonna hit its 10gB limit tonight, so went ahead and bought my 2nd sim card, I should be able to "live" with 2 10gB plans for now lol..... soon as my WWAN card arrives I'll update and let everyone know if it works!
StraightTalk wants $75 for 7gB of "tablet/laptop" data, or $55 for 10gB of phone data + calls/texts..... I get their way of thinking, "most" people wont max out the data on their phone, but 10gB is 10gB no matter how you use it, paying more for less is stupid. That said, I've been using straight talk for around 4-5 years now, was on CDMA sprint towers at first, then T-mobile, now using AT&T towers (best reception in my area), never had a problem tethering, just still not sure if the wwan card will work flawlessly or not, i'll learn soon

 

Well an update, the seller never shipped the WWAN card, I finally just asked for a refund instead.

Bought a 2nd simcard for my phone after I hit a little over 9gB, and started running it.... Now the new ones maxed out, actually up to like 13.9gB but still getting 4g LTE speeds (well, 6mbit download 60-80ms ping in my area) speeds.... Wont refill the other card until this one gets throttled or my service date expires (another like 12 days?)... They told me I was being throttled once I hit 10.3gB, but I still get the same speeds lol

Not too shabby for paying $55 for almost 14gB of data so far on the second plan. Sucks having to change my sim card every 3 weeks, but it'll sustain me until I move and have wifi at home lol....

I'll say this, at least 95-98% of my data usage is STRICTLY from tethering over straight talk, I rarely use my phone, I haven't had a single problem tethering in the 4-5 years of ST usage so far. As long as you have a phone that supports it, and/or it rooted and a program that allows it, you should be good to go

I happen to use a paid off cheap LG phone through T-mobile, which I called and had unlocked (super easy since its a legit paid off phone), so it can work on any GSM carrier. I run a Straight talk AT&T card as AT&T is a bit better in my area (imo).

re-edit, let me take that back, just checked my data, up to 13.99gB used, 12.78gB was to my tethering alone lol..... I've done everything from downloading movies, netflix, lots of facebook, onling gaming, torrenting, windows updates lol.....
