Hello. The machine is a full Netcom mobile phone, and part of the main and secondary cards, double cards can be blindly inserted, there is no problem with the telecom card in the card slot, but note that if you use the telecom card and other cards at the same time, set other cards as data cards and when surfing the Internet, the telecom card can not be connected.

R9S mobile card, China Unicom card, and telecom card can be used in any combination, any card can choose 4G network, and the other is mobile telecom 2G network or China Unicom 3G; Two telecom cards cannot be used at the same time.

How to upgrade your phone.

The new version is updated, and there are 2 ways to upgrade:

1.**Upgrade: You can check whether there is a new version pushed through "Mobile Desktop - System Update", if a new version is detected, you can click ** and install, during the installation process, the mobile phone will automatically shut down to ensure that the mobile phone battery is operated at more than 40%, otherwise it will prompt that it cannot be operated.

2.Manual flashing:

To back up data (contacts, text messages, etc.), you can back up through "Mobile Desktop--Cloud Service", or you can operate through "Tools--Backup and Restore";

Double clearing after the backup is completed: After shutting down, press and hold the power button + volume down button for about 10 seconds to enter the OPPO recovery mode, select Chinese Simplified - Clear Data and Cache;

Hello yo dear, I'll help you solve this late problem The specific solution is as follows:1: It depends on what version of R9S you have, there is a difference between mobile customized version R9ST and full Netcom R9S.

R9S full Netcom, support 4G 3G 2G 4G+, cards can be used together, when the main shirt card is 4G status for other cards, the other card can be up to other 3G VoIP status** status. 2: Two cards cannot be used at the same time:

When used at the same time, one card can use the 4G network, and the other card will not be able to register the network. If you use the network with a card that is not a telecom card, the telecom card will not be able to use the network. 3：

Due to the operator's requirements, when one of the two cards in the mobile phone is another card, only other Lundan cavity cards are allowed to use the 4G 4G+ network, and the cards of other operators can only use the 2G network. When there is no other card in the two cards, the SIM card of the other operator can be used normally. So you can't use telecom cards when you insert other cards into your phone.

Hope it helps
