The Dangers Of Buying Phones Made For China, India And Europe by atheistandproud(m): 7:23pm On Dec 21, 2021
The importance of network frequency bands on smartphones cannot be overstated. It is rather unfortunate that a lot of people do not know about network frequency bands and what they do.

Network frequency bands refer to the signal frequencies that are assigned to network providers. These network providers then use these frequencies to broadcast their signals.

Network providers are different across many countries. For example in India you have Airtel, Jio and Vi India, in Nigeria you have MTN, Airtel, Glo etc. and in the UK you have 3, EE, O2 and Vodafone. So where you live determines the network provider that you have to use. I live in Nigeria so therefore I can neither use AT&T nor China Telecom.

These different network providers also use their allocated network frequency bands to broadcast their signals to their subscribers.

What is the importance of network frequency bands on smartphones?

These days, smartphone OEMs tend to make different versions of the same phone for different regions. Two very good examples of companies that do this are Samsung and Xiaomi.

These different versions of the same phone usually only support network frequency bands in the regions that they are meant for. A good example of this can be seen in phones meant for India supporting LTE bands 1, 3, 5, 8, 40 and 41.

As earlier stated, I live in Nigeria so I am bound to use Nigerian cell providers like MTN (LTE band 7 and 20), Airtel (LTE band 3) and Globacom (LTE band 3 and 28).

It would make zero sense to me to buy a phone meant for the Indian region because apart from bands 3, it would not support my Nigeria LTE bands. If I buy such a phone, I would be forced to use a network provider with band 3 (Airtel), otherwise my phone would be useless as a communications device.

It would make much more sense for me to buy a device from the Chinese region (bands 1, 3, 5, 7, 8, 20, 40 and 41) as such a phone would support network signals from most of my Nigerian cell providers.

List of some selected countries and their supported network frequency bands

Nigeria
2G – GSM 900 and 1800
3G – UMTS 2100
4G – LTE bands 3, 7, 8, 20, 28, 40 and 42
5G – Nil

India
2G – GSM 900 and 1800
3G – UMTS 900 and 2100
4G – LTE bands 1, 3, 5, 8, 40 and 41
5G – Nil

USA
2G – GSM 850 and 1900
3G – UMTS 850, 1700, 1900 and 2100
4G – LTE bands 2, 4, 5, 12, 13, 14, 17, 25, 30, 41, 42, 46, 66 and 71
5G – Sub 6GHz (41 and 71) and mmWave (n260)

United Kingdom
2G – GSM 900 and 1800
3G – UMTS 900 and 2100
4G – LTE bands 1, 3, 7, 8, 20, 28, 32, 38 and 40
5G – Sub 6GHz (42 and 78)

China
2G – GSM 900 and 1800
3G – UMTS 2100
4G – LTE bands 1, 3, 5, 7, 8, 20, 40 and 41
5G – Sub 6GHz (78)

Conclusion
If you made it all the way to the end, congratulations. A big high five to you. So whenever you are going through the spec sheet for your next device, these spooky numbers won’t seem strange to you.

It is very important that you know the supported network frequency bands in your country and only buy a phone that can take advantage of them. This will save you a lot of headache in the long run.

It is quite clear that you do not understand the difference between network/region locked devices and network bands.

I'm not going to chastise you bro. I'll do my best to educate you.

Network frequency band support for a phone refers to the signal that it can accept.

Network lock means that the phone is locked to only one provider. Such phones phones may support other bands but those bands are rendered useless due to the network lock.

If I buy a phone that supports band 3, 7, 8, 20, 28 and 40 but is locked to Band 40. Unlocking it from band 40 will give me access to the other bands.

But if I buy a phone that only supports band 3 and 40 and is locked to Band 40. Unlocking it will not give me access to band 7, 8, 20 or 28. Because the phone has no support for them.

Common sense something.

Just because you don't understand something doesn't make it useless talk. Change your mindset.

I used to find it shocking when people came out to display ignorance in public but now it no longer surprises me.

If only you had been patient to read the comment above yours but I guess you were eager to drop your load.

Simple question.

If a phone like Realme 8 doesn't support band 7 and 20. How do you plan to unlock it? (Image A)

Or

If a phone like my old Tecno Pouvoir 2 that doesn't come with Band 28, how do you plan to unlock the band 28 that the phone doesn't support?

PS:

I'll make it easier for you. The band 7, 20 and 28 are not locked away. The hardware to support them is not present at all on the SoC.
