Question: Where to get a sim card
Document: You need to get a SIM card, it does NOT come with one.very reliable data speeds, and you save ATT's crazy 2 year obligation.I put a 32gig memory card in the unit and use it for backups as well.
This product excellent. Fast shipping too. It camefrom China and i was the first buyer. it is high quality. i took my att sim car , put it inside,and i was on the internet after it setup the enclosed software. i use it world wide also with rogers in canada and south america. all works with any gsm sim. i disconnected my home internet and use this because no wires,no modem issues, this keeps working by cell networks!
Great card. Can't buy it new anymore but it's very solid and will always prefer 4G if it can find it.
Once up and running, it ROCKS. The AT&T; Communication Manager software works well too.Note that if you don't already have a data plan and SIM card from AT&T;, you'll need to stop by a local AT&T; owned store to obtain them.
This hooked up without any problem and worked right away with my router.AT&T; sent me a note the next day that the higher speed would not really work until I got a new SIM card, and it would be free.The SIM card was free; and it DID make a difference, and I am happy!
This unit CANNOT be used with LTE (here in Fort Lauderdale, Florida), and AT&T; will not even put you through to data customer service if you give then your IMEI number. AT&T; states that it is NOT on their "approved list. "The only way to keep this thing working, at least for the time being, is to use an old SIM card, and don't tell AT&T; that you have the darn thing.
I've had this aircard for about a year and half, and it's constantly dropping connections with AT&T. When it was working, it would drop a connection once in a while, but now it won't stay connected for more than a few minutes. AT&T says it's a hardware issue with the card and that I have to buy a new one since it's out of warranty. No chance that's going to happen! No more Sierra air cards for me and no more AT&T broadband.
It is the only with the Band 13 AWS frecuency with good perfomance. The only problem is that  it get hot too fast
It wouldn't work with Apple OSX 10.8. Would have been fine if we could get it to work with the OS.
I am still unable to get an internet connection even with using the AirCard. I have windows 8 and it does not work with my computer. A waste of money.
Answer: yes
