I have an MHS291L Jetpack that is working well; I need a new battery for it and have one on order, but the batteries seem to be somewhat scarce. If I have to buy a new Jetpack soon, would a MiFI 5510 work as well as my current one? I have connections to my MHS291L filtered by MAC address; will the MIFi 5510 also filter by MAC address? Or would some other Jetpack be better?
Thanks.
