Hi Tim,
the latest Firmware for the Injector is http://download.peplink.com/firmware/fw_rsimServer_2_1.1.60.bin
I would recommend to update to this Version
The RC is the latest Version you can get - you found the right one 
Best wishes

Hello,
In addition is there an explanation on how multiple SIMs work in the remote management?
i.e. I have selected 2 SIM slots of the SIM injector to be dedicated to a modem (entered on separate lines as given in some note somewhere, but when you go back is shown in a single line). but how are they treated by the modem?
which SIM is actively used, what happens when data expires?, can they be alternated? etc…
Thank you,
Tim.

Hi Tim,
this is correct.
If you would like to use multiple SIM cards the separator would be space.
Example: xxxx-xxxx-xxxx:1 xxxx-xxxx-xxxx:3
You can see this in the Details of the Cellular Modul page of the Router. There is a line where the SIM-card details can be seen
Regards
Dennis

Hi Dennis,
Thanks, with the details of the cellular module page you mean simply which SIM card is in active use. Yes I see that, under the row “Remote SIM” and with it the adjacent detail below that row.
But this does not explain how
The active SIM can be chosen (if I now wish to use the other SIM allocated)
Under what conditions it chooses the SIM to use (no more data, periodic change?)
Thank you,
Tim.

Adding this post to this discussion about what I just learned from the support desk. Trying to keep it all in a single location about Remote SIM and SIM injectors.
Currently the SIM PIN is not supported in Remote SIM. expected fix in firmware ver 8.1.1
to get around this issue now is to first disable SIM PIN via a mobile phone.
Regards;
Tim.

I had the same question which I posted in another thread (below) but it wasn’t answered.
I am used to the granular control within the MAX Transit line of products, where you can set signal thresholds, bandwidth maximums, and other settings which would force a SIM change if one of those rules were hit.
Does the HD1/HD2 Dome honor those settings? In my testing, it does not seem to honor the signal level, and I have no idea how it would know the bandwidth amounts since that UI appears to be only for local SIMs.
The signal threshold is per cellular WAN setting. Therefore, it should work regardless where the SIM is coming from.
If you still see the device not working (perhaps on 8.1.0 RC2), please shoot a ticket and we can take a closer look at it. We have retested and seen it working on 8.1.0 RC2.
Thanks,
Eddy

I do see that signal threshold settings is defined at the cellular wan level.
However how about
That seems to be defined on Sim Card A/B and there isn’t an area for remote sim.

LTE/3G selection ,band selections or bandwidth allowance will not take effect for RemoteSIM connection. Request filed and Engineering team will consider the feasibility.

Hi @sitloongs
The following screenshots where taken over a three minute period and took the unit from LTE-A to 3G and then back to LTE-A by changing the LTE/3G setting from “Auto”, to “3G Only” and then “LTE Only”
This router is running 8.1.0 and the SIM Bank is on 1.1.60.
It would be great if the data fields which are not used when “Use Remote SIM Only” is selected where greyed out so that we know they do not have any bering on the connection e.g. Data Roaming which is under the Remote SIM Management menu. We also need the data roaming MCC introduced for RemoteSIM.
Would it not make sense to move the Remote SIM Management tab to the Cellular details page? This would be much more logical and easier to access settings.

Suppose all the settings in SIM Card A or SIM Card B should not take effect to the RemoteSIM connection. This is the reason why you need to enable the Roaming option , Custom APN in the RemoteSIM Management page. Do allow me to further clarify this and update back.

Hey @sitloongs
We need all the usual settings available when using RemoteSIM.
From our testing, the following is currently the case;
Carrier Selection - Works for both Physical SIM & Remote SIM from main cellular details
LTE/3G - Works for both Physical SIM & Remote SIM from main cellular details
Band Selection - Works for both Physical SIM & Remote SIM from main cellular details (tested and confirmed today)
Data Roaming - Set for Physical SIM on main cellular details / Set for Remote SIM under remote SIM Management
Authentication - Not tested
Operator Settings - Set for Physical SIM on main cellular details / Set for Remote SIM under remote SIM Management
APN / Username / Password / SIM PIN - Set for Physical SIM on main cellular details / Set for Remote SIM under remote SIM Management
Bandwidth Allowance Monitor - Set for Physical SIM on main cellular details / Not available for Remote SIM (need some way of monitoring Remote SIM usage on the device)
All the options above which are “Set for Remote SIM under remote SIM Management” should be greyed out on the main cellular details page when “Use Remote SIM Only” is selected with a note/warning “These settings can be found under Remote SIM Management in the advanced section”

Hello @Harry_Thompson,
We have been working with @sitloongs and several of the Peplink team in the firmware and other members here in the forum in improving the documentation.
Great to read your discoveries and thoughts, they are well received.
Happy to Help,

Hello, I would like to ask this question again.
In the cellular detail page I can allocate 2 slots of the sim injector dedicated to the particular modem.
But what are the conditions of their use?
Why would I allocate 2 SIM slots? is there a process of which SIM would be the active SIM? Under what conditions is one slot chosen over the other?
Thank you,
Tim.

Hello Tim @tgorter,
As you have discovered, you can alocate lots of SIM Injectors and multiple ports into the config
At the moment the greatest use is for where people are using Prepaid SIMs, for all other SIMs, there is currently no advantage that I can find except to offer the SIM as a fail over between different carriers.
Peplink are working on improving this functionality, we too look forward to applying all the flexibility to the Remote SIMs as is available with the Local SIMs.
Happy to Help,
Marcus

Can we get a confirmation on the support of PIN code in release 8.1.1?
My tests with a MBX are failing.
Thx
Awesome - thanks for letting us know.
Any idea of release date (or Beta) ?
What about Data Limits on Sims and how to disconnect one Sim after it reaches it Data limit to shift to the Next Sim ?
