Mainstream brand smartphone 4G frequency band, 4G+, and volte support statistics
This article aims to record the 4G frequency band and volte support of major models of well-known brands to facilitate everyone to query. Personal strength is limited, everyone is welcome to correct and supplement.
1. Currently, domestic 4G full-band and all-network mobile phones usually support:
FDD-LTE: B1, B3, B5, B7, B8;
TD-LTE: B34, B38, B39, B40, B41 (2555~2655MHz);
①. There is no B7 frequency band in mainland China, but the frequency of B7 of FDD and B41 of TD overlap,
There is B7 in Hong Kong and Taiwan. In fact, many manufacturers have done it by the way, which is quite good.
It is also not ruled out that the three major operators will re-cultivate the 2.6G frequency band into FDD in the future.
②.B41(2496~2580~2605~2690) is actually a long frequency band. China
only has 100M of them. Therefore, in order to distinguish this post, B41
of the Chinese frequency band is written as B41, and the full full frequency B41 is written as B41+.
2. Mobile 4G frequency band:
FDD-LTE: B3, B8;
TD-LTE: B34, B38, B39, B40;
③. Mobile B38 is actually a real subset of B41;
④. Mobile has obtained the FDD license, and it is only a matter of time to promote re-cultivation B3 and B8;
⑤. Only China Mobile in the world has B34 and B39 frequency bands, so you need to pay attention to buying parallel mobile phones;
⑥. Mobile carrier aggregation 4G+ is in-band aggregation;
3. Unicom's 4G frequency band:
0 FDD-LTE: B1, B3, B8;
TD-LTE: B40, B41;
⑦. China Unicom's B40 is not used for the time being;
⑧. China Unicom's carrier aggregation 4G+ has both in-band aggregation and interband aggregation;
4. Telecom's 4G frequency band:
FDD-LTE: B1, B3, B5;
TD-LTE: B40, B41;
⑨. Telecom's B40 is not used for the time being;
⑩. Telecom's carrier aggregation 4G+ is interband aggregation;
5. Dual-stop full-network difference:
①. [1.0]: Main card three networks 4G, Sub-card Mobile Unicom 2G, Telecom can only be the main card, and cannot change the
card slot location, and cannot dual telecom;
②. [1.5]: Main card three networks 4G, Sub-card Mobile Unicom 2G, Telecom can only be the main card, and cannot dual telecom;
③. [2.0]: Main card three networks 4G, Sub-card three networks 2G, and
④. [3.0]: Main card three networks 4G, Sub-card three networks 2G, and
The secondary card can support up to Unicom 3G, and cannot be dual telecommunications;
⑤. [4.0]: Main card three network 4G, secondary card mobile telecommunications 2G, or China Unicom 3G, and cannot be dual telecommunications;
⑥. [5.0]: Main card three network 4G (please turn on volte for dual telecommunications, otherwise there will be problems with the call);
Note: The version number seems to be named by Xiaomi, and it is very vivid and specific, so let's take it as a standard.
Since China Unicom has begun to withdraw 2G, it is best for dual-slot users to buy mobile phones, starting from 4.0.
6. Mobile Custom Version Full Network 4G+:
⑦. When there is a mobile card, you can only use the mobile card to access cellular data;
⑧. Some models of mobile Custom Version Full Network and Public Version Full Network 4G+ support are different from 4G+ support,
For example, Nut 3 only mobile Custom Version supports 4G+;
⑨. Some models of mobile Custom Version can be changed to Full Network Normal Version by flashing or flashing Qualcomm NV value to Full Network Normal Version,
.
.
.
. Unlock FDD-LTE B5 and B8:
. Some Qualcomm processor models whose antenna hardware is not castrated can change the baseband NV value through Qualcomm's official tools. Unlock B5 and B8, such as:
①. Xiaomi 5, Xiaomi max, nubia z11 unlock B5 and B8;
②. Xiaomi 5s plus, Xiaomi note2 (non-global version), Redmi note4x (Qualcomm version) unlock B8;
Unlock method: http://www.miui.com/thread-7640160-1-1.html
[This post is missing, the value of 06829 should also be changed to the same value as 06828.】
Note: In fact, modifying the NV value is just to untie the soft shield. If the hardware antenna does not support it, the unlocking is also invalid. For example, the unlocking of the Redmi 4 high-end version does not have B5 and B8, and
For example, B20 and B39 both require separate filter hardware support, so the Chinese mobile phone unlocking B20 or
Parallel mobile phone unlocking B39 is basically useless,
Please test the specific situation yourself, theoretically, the phone will not be damaged;
8. Others:
There are five operators in Taiwan: China Telecom , Taiwan Big Brother, Yuanshi Telecom, Taiwan Star, Asia Pacific Telecom, 4G frequency bands including B1, B3, B7, B8, B28, B38... The three except China and Taiwan Star all use B28 as the main 4G force and volte, so go to Taiwan to play and buy the card of China Telecom.
The United States has many 4G bands, but it is mainly B2, B4, B5, B12, B17;
The main frequency bands in Europe have more B20 than in China, and B28 in the Asia-Pacific region.
parallel mobile phones basically do not support telecom CDMA and mobile TD-SCDMA, and rarely support B39. They usually can only perfectly support China Unicom, such as the Snapdragon 820 international version of HTC 10. Finally, remember not to buy a card sticker or a lock machine when buying a parallel mobile phone.
