Three Slower than Smarty?

Hi,
I've been using Smarty for over two years as our main Internet connection. Just switched to Three on a 12 month contract, the reason being to get a real IP address. I was fed up with applications not tolerating the second by second IP address changes on Smarty's CGNAT.

The downside is that I can no longer pretend that it is not significantly slower. I tried to convince myself that it was just random variations, but after a month it's perfectly clear.

For reference we receive only B20, RSRP is around -83dB and the mast is just over 6km.

Has anyone else found a speed difference? Either way.

If you could change your apn from three.co.uk to 3internet that should improve things, it certainly does for me.

Edit: on my Three sim I set to 3internet as three.co.uk was terrible.

@CarlO1460 I think that's what he did already in order to avoid the CGNAT frequent IP changes... It's possible the 3internet APN is slower in your case for whatever reasons (I've certainly read about this on the forum in the past).

Interestingly, 3internet APN works on smarty. Try it yourself

All APNs (three.co.uk. 3internet, mob.asm.net) worked on Smarty but didn't make any difference to the behaviour. I think I've seen it suggested that you can put anything you like and it still works.

On Three I'm using "3internet" as I think that's the only one that gives a real IP address. Changing to "three.co.uk" doesn't affect the speed.

I'm finding Three is running very bad last couple of days on certain groupings of masts....

By groupings, I mean....

Generally I've noticed that Three's own branded masts and monopoles have a 3 digit eNB and then MBNL/CellNex masts (shared with EE commonly) normally have 4 digit eNB's and then there is 5 digit eNB masts which speculate in my area tend to be masts that run off the 4 digital ones.

I've been finding last few days that service is impacted on Three's own masts (ones with 3 digit eNB's) even new 5G enabled masts are acting strange.

I tried changing from CGNAT APN (three.co.uk) to the IPv4 APN (3internet) and speeds drop lower though where more stable.

FYI: By slow I mean 1-2mbps as low as 0.1mbps on the 3 Internet APN.

Talking of Smarty, don't think I'm going to make it till the end of the month, quite looking forward to seeing if all data stops on the 1TB mark or if it's truly unlimited now.

What does everyone think? :unsure:

I'm plumping for a smacked bottom and no more data. :cry:

When I use LTEInspecteur it shows two IP address under the Network heading. When using 3internet both addresses are the same and are real addresses.
When using three.co.uk they are different, with one address 10.xx.xx.xx or 100.xx.xx.xx which I presume are both CGNat and the other a real address, currently 92.xx.xx.xx
I'm not sure what this means in terms of MIMO but using two different paths could conceivably improve performance.
Does anyone know what's going on?

Good luck TWB if you breach the 1TB

@TheWeeBear EEEK! That doesn't look fun. Let us know how it goes and ill probably be able to hear you sobbing from Bradford 🤣🤣

Seems to have recovered, so it was maybe a red herring. There have been periods where Smarty ran slow so it was maybe just a coincidence that this corresponded with swapping from Smarty to Three. Fingers crossed. Although I changed in order to get a real IP address, it would be a bummer to have been stuck with a significantly poorer throughput.

Three has priority over Smarty, this is easily identifiable generally where Three won’t sell you a 4G hub on thier website checker due to over saturation expect Smarty to perform nothing like a Three contract.

Obviously variations on base transmitters mimo etc & the hardware used by the end user make a difference, using numerous top spec QAM/Mimo hardware devices in saturated areas can show the real Smarty difference to Three contract sims.

You may also be in a saturated area if you cannot order a 4G Hub, but oversaturated areas defo do not allow a 4G Hub order.
