Speed on my Mobile Data SIM

Hi

 

I bought the 200 gb mobile data SIM last Friday with the aim of replacing my existing ADSL connection with the faster 4G+ mobile connection (no NBN in my area). When I bought the service in store I was told that the speed would be equal to what I am experience from my mobile as it is on the same network (optus mobile customer too). I bought the Huawei E3372 mobile with the SIM. 

 

When I got home I was surprised that the speed I am getting from the modem  was significantly slower than my phone. So instead of say 50 - 80 mbps which is what I get on my phone I would get 20 mbps if I'm lucky but more often it would be 4 - 5 mbps. 

 

All I want to know is why, what can I do to improve the speed and if its due to the modem should I invest in a CAT6 modem ? 

 

I've spent an hour on hold with optus and spoken to about a dozen optus tech assist. No one is giving me a straight answer! I've tried a SIM replacement, modem replacement, usual line that there are upgrades in my area and strange lines that "the speed is acceptable as it is faster than 512 kb/s which is what optus considers to be slow".

 

Any help would be appreciated.

 

Thanks,

Re: Speed on my Mobile Data SIM

Is the phone with Optus and are they both getting similar reception? I did read somewhere the E3372 is capable of up to 150 Mbps I think so I'm not sure there is any advantage in investing in a faster modem.

Yes the phone (Samsung S7 edge) is with Optus as well. 

 

Both have similar reception. I've tested both out by putting them on the table and running a speed test side by side. the difference in speed is steggaring.

Re: Speed on my Mobile Data SIM

I did notice a difference with my Telstra phone over my Optus phone however I didn't notice any difference in speed between my E3372 on Optus and my Optus mobile. To be perfectly honest it was probably something I wasn't looking for. I have a new Cat 6 modem floating about somewhere so I might have to try a comparison.

Re: Speed on my Mobile Data SIM

Hmm surprising results with the CAT6 clearly showing a difference with the speeds. I also did a Telstra test just for good measure.

Re: Speed on my Mobile Data SIM

HI @Henry2018 - The speeds can vary as the two devices have different capabilities. Although, both use same network but Huawei E3372 is a 4G device only and Samsung S7  is a 4G Plus and can use multiple frequencies (LTE 700 / 1800 / 2100 / 2300 / 2600 MHz). I'd also recommend checking your coverage and speeds at different places and different times  to see if the speeds are any better.

Re: Speed on my Mobile Data SIM

Hi Aman

 

What you said make sense but just frustrates me more as the E3372 modem is marked as a 4G plus modem on the Optus website, the store and by your technical staff/sales staff.

 

I beleive the samsug S7 edge is a CAT 9 device so that would expain the difference in the speed between the two (E3372 being a CAT4). I just wish Optus was upfront with me and told me at the start. I would have bought the CAT6 modem you are selling and be happy with it.

 

Speeds are better in the morning and I totally accept that.
