IR32 Roaming test platform
The IREG test specifications have been released to verify inter-PLMN roaming between mobile networks. IR.24, IR.26 and IR.27 contain the tests for circuit switched services, supplementary services and fax/data services. IR.35 contain the tests for 2.5G and 3G packet switched services. IR.32 defines test for CAMEL interworking, the basis for international roaming with prepaid cards. The successful execution of these test suites is a prerequisite for an international roaming agreement between mobile network o
CALL, USSD AND CSFB
RoamNest log will tell you when is radio access changed form LTE, 3g or 2g. It is important to see how fast is return to the LTE for example during CSFB testing. Other option how to invoke CSFB is to use USSD code you will just simply type it instead of callied number.
Download and upload speed is tested towards server in the internet. For speed testing purpose it is possible to create your own test site. For detail, please check server section.
Ping shows you if certain host is reachable. You can use IP address or DNS name of the host. There are both IPv4 as well as IPv6.
SMS test alows you to send SMS using default or user defined SMSC. Log contains information regarding MO (Mobile originated) MT (Mobile terminated) phase. In MT phase you can see SMSC address of the SMS centre used for the delivery of the message.

You could run all three wan connections on a bonder interface. You will need to build three tunnels back to a data center or remote location and build the bonder interface on the remote side also.
Expect latency and jitter over head. You will not see a huge increase in bandwidth but it will be better. I typically see 1/3 loss. So three solid 10 mbps connections, you would likely see around 15 to 20 mbps.
Its also important to note, when using a bonder interface, typically your weakest link can effect everything else that being said, all three connections must be solid. OR
use something like ipsec tunnels with ospf and ECMP to load balance. Problem is ECMP expects all links to have equal quality/bandwidth. if some links have more bandwidth, you'll have to setup additional tunnels on those interfaces to simulate them as more prefered. Setup a RouterOS VM in the DC then you can do eoip ipsec tunnels easy. If you have to punch through a firewall, sstp should work.
