Yes, you can use multiple devices at one time.
I have issues with Straight Talk and do not recommend.
1. Your data plan MBs do not rollover when you add more, in other words you have to run out before you can upload a new card or you wasted data.
2. The Hotspot, if not used for a week or so, loses connectivity to the networks and you have to waste 20 minutes calling Straight talk tech support to "update" your account information. It is ridiculous.
yes...we usually have three tablets connected to our unit...and time is determined by the amount of data you purchase and burn through...
carroll, sure, your wife can spend all the time she wants formatting her Facebook page but remember, you have to pay in advance for the amount of data you use. Facebook, in general, will not use a tremendous amount of data but does use some as there are photos to upload, etc. …and if she is uploading videos, even though compressed, it could use more data than photos. But generally, uploading photos and such isn’t as much of a data hog as streaming videos or transferring large files so it shouldn’t be too expensive in terms of purchasing service cards for this hotspot if only using it for Facebook activities, web surfing, e-mailing, etc.
Yes, you can use both of your computers at the same time. Up to five devices can use this at once. However, the more devices connected, the slower the speed for each device.
