Much head scratching, searching and finding the Service Mode for the phone [https://android.stackexchange.com/questions/102077/how-to-safely-activate-lte-on-s4-mini-gt-i9195-running-4-2-2], finally tried changing the SIM MCC/MNC - mobile country code, mobile network code [http://www.mcc-mnc.com/]. The Sysmocom SIMS come with 901/70 which looks like Satellite Network, unused network code. Tried the default OAI MCC/MNC 208/93 France, Unused network code, also UK, no luck. Tried a US code and got the LTE option but would not register. Finally discovered the IMEI of the phone contains a code for the country or origin [http://www.samsungsfour.com/tutorials/find-out-galaxy-smartphone-country-of-origin-from-imei-code.html], which in this case turns out to be Finland - tried a carrier there 244/91 and during tests with the easy to setup OpenLTE found the network "FI SONERA" finally. So the target UE likes 244/91 OK. Another helpful tool is the phone service mode mentioned above, *#0011# and then hit (menu) Back and then (menu) Key Input and enter Q0000 and wait. Then Select UMTS -> Debug Screen -> Phone Control -> Network Control -> Band Selection -> LTE Band and can pick 3,7,8,20 or * to narrow and speed up the network search. <br/><br/></div></td></tr>
