I bought a SIM from
Free Time Telecom GmbH | SIM Karte Multi SIM IMSIkarte SIMtravel Globalsim im Ausland bis zu 70% Handykosten sparen.
The SIM has 3 IMSI's and came with 3 numbers:
IMSI starting with 262.03 (e-plus)
IMSI starting with 295.05 (Mobilkom Liechtenstein)
IMSI starting with 310.630 (Cellular One)
Amerilink Wireless is now called Cellular One and serving this area:
Amerilink Wirless - Local Coverage Map
One can switch between the IMSI's with SIM Toolkit, menu "Multi Account".
Being in Germany, the SIM only registers to a network (e-plus) when switching to IMSI 262.03. The display shows the network-name as "Germany", which is indeed e-plus.
One is reachable by all 3 numbers:
+49 1570
+423 663
+1 940
Would be interesting to which networks - using which IMSI's - the SIM registers in other countries.
