this seems to be a good frequency overview of the german networks:<br>

<br>
...including UMTS + GSM.<br>
<br>
I currently use T-Mobile (GSM900) and have a backup SIM card of
E-Plus (GSM1800).<br>

The modem module we are currently using is a GSM/GPRS module - the
SIMCOM SIM908. This is a quad band module, so compatible with
everywhere. Very nice, and works well, but I am aware that the
global cellular providers are moving away from 2G and long-term
this may be a problem.
<div><br>
</div>
<div>The replacement SIMCOM module seems to be SIM5320. But, the
frequencies seem more complex. Frustrating as we don't need the
3G speed - but we do need the frequency compatibility.</div>

<div>There appear to be three variants of the module:</div>
<div><br>
</div>
<div>
<ul class="MailOutline">
<li>SIM5320A<br>
Dual-Band UMTS/HSDPA 850/1900MHz<br>
Quad-Band GSM/GPRS/EDGE 850/900/1800/1900MHz<br>
* FCC<br>
* PTCRB<br>
<br>
</li>
<li>SIM5320E<br>
Dual-Band UMTS/HSDPA 900/2100MHz<br>

* GCF<br>

<br>
</li>
<li>SIM5320J<br>
Dual-Band UMTS/HSDPA 850(800)/2100MHz<br>
Quad-Band GSM/GPRS/EDGE 850/900/1800/1900MHz<br>
* Telec<br>
* JATE</li>
</ul>
</div>
<div><br>
</div>
<div>From the certifications, I'm guessing SIM5320A is USA and
SIM5320E is Europe.</div>
<div><br>
</div>
<div>
<div>There is also <a moz-do-not-send="true"
href="http://wm.sim.com/producten.aspx?id=1026">SIM5218</a>,
which appears to have similar features but is
tri-band UMTS/HSPA850/1900/2100 or UMTS/HSPA 900/1900/2100 as
well as GSM/GPRS/EDGE 850/900/1800/1900. It is more expensive
and twice the size of the SIM5320.</div>

<div><br>
</div>
<div>From my limited research, it seems AT&T is using 850 and
1900, Three in UK is using 2100.</div>
<div><br>
</div>
<div>Anyone know what the major carriers around the world use?
What about the ones you are using now?</div>
<div><br>

<div>P.S. By comparison, the iPhone5 is MTS/HSPA+/DC-HSDPA (850,
900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE
(2 variants, with a few bands each).</div>
