Range Router vs Phone (Galaxy S6, S9, Huawei B525): Which Provides Better Connectivity?

Hello
I'd like to know what would be better:
Phone, e.g. Galaxy s6 or Galaxy s9 or huawei b525 router, e.g. with 2 internal antennas

Better range of what?

I meant huawei 525 already corrected.
And I'm talking about the Internet. Will the router without the antenna get the same speed or higher than the phone

The router has an advantage if only because you can force a specific band - anyway, put both devices in the same place and check it, you will find out.

After all, S9 has 4CC CA, MIMO4x4, QAM256 and B525 only 2CC CA without MIMo4x4 and QAM256, so what is there to compare? In addition, it is important what the operator offers on the BTS you use.

I don't have Huaweia yet and I just don't know whether to buy or use lte on my phone.
And it's on the transmitter
3x1800
3x2100
3x2600
Everything orange just like my sim card

You have already received the answer, the signal parameters on high LTE bands are weak at your place and very weak on LTE2600, so regardless of the choice of router, the external antenna is the basis. With such signal parameters, there is no chance to take full advantage of the possibilities offered by this BTS, even on the phone.

I understand, but I'm just wondering if the router without an antenna or with antennas attached to it will have similar speeds to the phone? Assuming both are set to the same lte bands

If the s9 aggregates 3CC CA even in MIMO2x2 on LTE2100 + 2600 + 1800, the B525 at home has no chance to achieve such speeds on 2 CC CA MIMO2x2 with LTE2600 + 1800. Improving the signal on LTE2600 and LTE1800 will improve the signal on B525 and probably on the speeds achieved, but no one will answer how.

And assuming that I only use e.g. 2600?
Does a router have a better antenna than a phone?

And what does it matter? The antennas in both have a similar gain, at home you have a 2600MHz RSRP -113dBm on the S9, even a 2 or 3dBi better signal on the B525 does not change anything, such a signal is still far from optimal parameters. in mobile internet in such conditions, with such a signal and distance from the BTS, external antennas are used if you want to have a stable and optimal connection. I use 3CC CA LTE2600+2100/1800+800, I have optimal signal parameters and in Play I achieve DL 150-230Mb/s. On 2 CC CA LTE2600+2100 about 180-200Mbps. BTS unloaded, deterioration of signal parameters by 10dBm usually results in a significant reduction of DL and even greater UL.

Now I have -100dBm on my phone and 1080p videos on youtube work ok
And on a modem without an external antenna, I will also have a similar result, right?

But as a baseband you have LTE2100 and not LTE2600, sufficient signal, DL in LTE2100+2600+1800 aggregation so no problems. On the B525 you will have at most LTE180 + 2600 and it's hard to say if DL will be comparable, you'll do the test and you'll see. this is a radio, besides the speeds depend on the load on the BTS and are variable and the load rather increases over time. There are just more customers. therefore, it is essential to optimize the signal parameters with an external antenna.
