Hi Vaughan, I don't know if it works out any more effective, but all of the current mobile plans (voice+data) have a data cap, but when you exceed it, it shapes you down to 1.5Mbps. If that is sufficient for your needs, it may be a cheaper option than having a "data" SIM.

Unlike some of the commentary I’ve seen on this list. Rather than a USB dongle (which we had some issues with previously) we use a Huawei 4G Router (B525), which connects to a Mikrotik via a LAN port. The B525 has proven to be a very robust device and I would recommend it (govt security concerns aside). With the B525 you supply a SIM card. To date we have been using Telstra via M2M One, which has been quite reliable except for one huge outage which took their network down for a few days – some months ago now. The issue with the Telstra SIM is that while the data is unlimited – so it is a scalable solution, the data charges are also pretty steep. So I’m interested in what alternatives others might be using - I recently saw some comments about prepaid dongles with Optus or Telstra, this wouldn’t be my preferred option, but I am interested to know what they cost and what they provide - More interested in SIM card service providers (i.e. alternatives to M2M One / Telstra that would be more affordable in the event that a backup link switched to primary) Cheers, Vaughan _______________________________________________ Public mailing list Public@talk.mikrotik.com.au http://talk.mikrotik.com.au/mailman/listinfo/public_talk.mikrotik.com.au
