Data Throttled Abroad

16: Advanced member

I was in France last week and I was getting speeds over 100mbps quite regularly on SFR and Bouygues roaming using my Vodafone UK SIM only contract.

Thanks for the data point PedroC; this helps.

Just as a side note, I travelled to Cyprus yesterday and having checked the Vodafone website, I was advised that Cyprus wasn't a 4G destination.

I was therefore really surprised (and of course pleased) to see that Vodafone got it wrong it seems!

I have 4G roaming with Cytamobile-Vodafone and decent 4G speeds. Compare that to others in my group who aren't with Vodafone who are stuggling to get 3G coverage with MTN Cyprus.

Well done Vodafone - sometimes I like it when you're wrong :smileyhappy:

I've been running more tests. In the last few days the data throughtput has been around 2-3Mbps DL on SFR 4G. It's 4:30am at the time of writing this entry. My data throughput has been around 16-18Mbps on DL for the last 2 hours. This is the sort of performance I expect to have at my location. I'll run some test again later today during normal hours.

Throughput is now back to the 2-3Mbps; could it be down to network congestion then ?

 

I've noticed that the IP address used by Speedtest is Vodafone 148.252.129.171 and the Server is always in the UK. Does this make sense ?

 

Thanks

A couple of hours ago I was getting 115mbits in download here in Italy with my Vodafone UK sim. Now, this. In the same location.Screenshot_20170808-121402.png

The part I am unsure about is I appear to have a UK public IP address whilst my physical location is France. Does this mean all of my traffic is routed to the UK before it breaks out to the Internet? The other thing is that with a UK public IP address access to UK based service that would otherwise be barred from abroad is fully enabled. Any thoughts ?

Yes, when roaming your mobile data is routed through the UK which is why you get a UK IP address. 

In fact, a lot of your home network's infrastructure is used even when you're in another country.

Thanks PedroC - I thought so; it could contribute to the degradation in performance between day and night time. Is there a way to obtain a local public IP address and breakout locally rather than going back to the UK ?

The whole evening roaming has been COMPLETELY dead here in Italy. Speedtest won't even start, netperform shows 0.0mbps in download and not a single webpage will load. I'm using WiFi at the moment. You can also see the speedtest i did this morning on netperform (almost 115mbits download). Screenshot_20170808-211357.png

Same scenario here in France. The data throuhgput has gone sub 1Mbps and pretty much unusable for anything beyond emails. The performance is the same whether on SFR 4G (full bars i..e. optimal radio signal strength) or on Bouygues 4G (4/5 bars radio signal strength). The common denominator is Vodafone UK traffic going back to the UK.

 

Can someone in Vodafone confirm what the issue is ?   

 

 

Thanks

@JOHN-1970 @amh13 Is this issue consistent across 4G and 3G?

Yes, I am having this issue con both 3g and 4g. Upload speeds are regular, as you can see I easily reach 20-30mbits on 4g, but download speeds are extremely low. All afternoon I have been barely getting 2-3mbits on both 3g and 4g, and later on in the evening internet completely dies (both 3g and 4g). 

 

As said, this is not a problem with Vodafone Italy, since with a local sim I easily get 100-150mbits on 4g in the same location.

Hi amh13. I concur that it is unlikely to be the 3G or 4G local network. 

 

Once again can we get a confirmation/validation from Vodafone UK please?

In my opinion Vodafone is failling to deliver a service that is in keeping with 4G data throughput/performance and customer expectation.

 

What are your thought on this based on your experience of the Vodafone data roaming service?

I am back in the UK having spent nearly two weeks roaming with my Vodafone UK SIM. I visited France, Belgium, Germany, Austria and the Netherlands and performance was absolutely super in all of them, I was regularly sustaining over 100mbps on many of the high spectrum sites.

Well Pedro good for you but I do not share your experience unfortunatey for me. It appears that I am not the only one either.

I recently spent a week in Bulgaria as well. There, I also noticed that performance dropped heavily in the evenings, even though I had full 4g signal. Speeds dropped from 65-70mbits in the morning to about 5mbps in the evening. I never complained about this, because it was still perfectly usable. 

 

Here in Italy, however, my speeds are consistently over 100 Mbits in the morning, and then drop off to about 2-3mbits in the afternoon before completely dying around 8 o'clock in the evening. At the moment I'm using WiFi. 4g/3g is completely dead, the speedtest won't even start and all webpages time out. 

 

This is not an issue with local network, because as said before, testing a local Vodafone SIM consistently gives me results around or over 100mbps regardless of the time of the day

@JOHN-1970 @amh13 We may be able to look into this for you - so we're able to check this, please answer the following:

- How long are you abroad for?

- Are you around the same location for the duration? 

- If so, which location are you in? 

Please also try to complete a manual roam and flick airplane mode on for 10 seconds and then off to try and reconnect to the network.

Hi, I have been abroad for a month now and have been having these speed issues for the past 3 weeks.

 

I have travelled in Switzerland, Bulgaria and Italy, and the problem has been present in all of these locations, with Italy being the worst (in italy the connection often completely dies or is under 1mbit, in switzerland and Bulgaria speeds dropped to about 5mbits in the evenings but never below). My account has 2 numbers, and both have been having the same issues.

 

I also have a spare Vodafone Italy sim card and tested this in Italy, Bulgaria and Switzerland (on roaming) with no issues whatsoever. Speeds never dropped below 50mbits in any of these locations, even when my UK sims were not working or very slow.

 

I have tried resetting my phone, doing a manual roam and also resetting the network settings on my device; however the problem persists and is present on all of the roaming partners.
