There are several dual-SIM Lumia phones which support LTE, 4G and 3G. However, only one of the SIM cards can be set to use LTE, 4G or 3G connection at any given time. The other SIM is restricted to a 2G/GSM connection. If your mobile operator doesn’t have a 2G/GSM network, the SIM card registration will fail and you won’t be able to make or receive phone calls, text messages or use mobile data with this SIM card.
For information on SIM card compatibility with 2G/GSM networks, please contact your mobile operator.
