Does going with the EHS5-US and the EHS5-E provide global coverage? | Telit Cinterion IoT Developer Community

Our product is targeted at the US healthcare market initially and we desire to have the most barebones 3G offering so that we can use AT&T's network in the USA. The EHS5-US is a good solution for this. When we go to extend our offering to the rest of the world, will the EHS5-E provide me global coverage?
We use an MVNO to provide our network access (KORE Telematics). They have relationships with many carriers around the world. I'm looking for a very solid understanding of where my product can be used and if there are any limitations going with the two-pronged approached with both versions of the EHS5 module.
Additionally, I understand that the EHS5-US and EHS5-E have identical foot prints. Are there major software differences to consider? Can anyone point me to products that implement this two-pronged approach with the EHS5?
Thank you!

Hello,
according to Hardware Description and AT spec discussed products operate on following bands:
EHS5-E:
GSM/GPRS/EDGE: Dual band GSM 900/1800MHz
UMTS/HSPA+: Dual band UMTS 900/2100MHz
EHS5-US:
GSM/GPRS/EDGE: Dual band GSM 850/1900MHz
UMTS/HSPA+: Dual band UMTS 850/1900MHz
So EHS5-E and EHS5-US may operate in all most popular bands, but it doesn't offer absolutely global coverage. I'm afraid that you'll have to perform deeper research and confront supported bands against local networks to be sure that this solution will work.
Footprints are the same, even Hardware Description document is common for these products. There are no major SW differences.
Hope you find my answers helpful. Good luck designing your application!
