I have a new sim card from Straight Talk, that supports LTE/4g and i'm running Jellybean Sandwich v2.0 on my Note. With this new sim and updated APN settings I'm still getting only typical HSPA+ data connection, no luck on getting LTE to work yet.
Under Phone info (*#*#4636#*#*) menu settings I cannot switch a preferred network type, it goes back to "WCDMA preferred" all the time. Already have tried another modem (UCMD3) with no success whatsoever, it won't let me select anything else. I'm getting the same HSPA+ connection.
Any advice on how to get LTE to work, please?
