Can't Access Network Abroad
Hi namsoni! I'm sorry to hear that you can't connect whilst in Tanzania!
Unfortunately, as we do not control the network in other countries outside of the UK, we cannot always guarantee the service, if any, that you will receive. This is because we do not have access to the infastructure or network capabilities within the area.
However, we'll always try our best to get you connected to a network while you're abroad!
As Tanzania is outside of Europe, you will also need to have your International Access activated on your account. Without this being activated, you will be unable to access any internaitonal networks.
I would be more than happy to check your account for you namsoni, so please don't hesitate to drop me a PM and i'll look into this for you -Sean 
Hi MisterW, thanks for getting in touch!
Roaming can be turned off whilst in the UK, however, it'll need to be turned on if you're abroad.
International Access must be activated if you wish to make calls to other countries whilst you're in the UK, as well as if you where to travel abroad. Whilst abroad, you won't be able to connect up to a network if your International Access settings are not turned on.
I hope this clarifies everything for you! -Sean
You're right in saying that Roaming is not needed if you're in the UK, however, some of our customers like to have the option to turn this off.
In the previous instance, I was making reference to the fact that Tanzania is not a part of Roam Like At Home as it's outside of Europe. Therefore, to connect up to the network there you'd also need to have your International Access option activated too.
I hope that this helps further! -Sean
@SeanCorri thanks for the response

I can see why you would want to disable 'data roaming' but that's done on the phone, not on the account!. I can't see why you would want to disable roaming completely
. Surely if you don't want roaming, either don't take the phone abroad or turn it off! If roaming is disabled on the account it's useless abroad anyway!

So to be clear 'International access' is NOT required in a RLAH country ? and you'll still be able to make calls to ANY RLAH country ?
It's no problem at all MisterW!
I have heard of some cases where people who live in the South of England can pick up French network signals! I think it'd be a handy feature for them to turn off their Roaming so that they don't incur any additional charges.
If anyone does decide to have their Roaming turned off, then they can simply get in touch with us via Facebook, Twitter, Live Chat on our website, or give us a call on 0800 0791133 - Option 1 or 500 from their Plusnet mobile number. The great news is that Plusnet customers can call 500 from anywhere in the world, for no charge! It usually takes no longer than 2 hours for the Roaming service to become active!
To confirm, the only instance that you would need International Access on within a Roam Like At Home country is if you were to call or text a non-Roam Like At Home country. For example, if you were in France and called a number in Australia, this would require your International Access to be turned on -Sean
Actually would you not possibly have the same issue if (for instance) you were on the Eastern border of Poland and picking up a mast in the Ukraine? At least with International roaming turned off it wouldn't cost you anything

I had considered that, since I encountered a similar problem some years ago. However, now that RLAH is in place there would be no extra charges. In fact you could actually save money if you needed to call a French(or other EU number) by ensuring that you were, in fact, roaming. Then the call would be included in your allowance, rather than £1/min when in the UK!

but, if you're outside the UK, you can't call 500 from your mobile because you can't connect to a network - catch 22! Calling the 0800 number probably isn't an option and whilst using Facebook,Twitter and possibly this forum does work eventually (once you've gone through the backwards and forwards to clear security), what's really needed is a facility on the account portal to enable/disable these facilities, or at least send a secure message...
Hi MisterW!
If customers are still connected to a foreign mast after an extended period of time, we'll usually request an update from the customer as to whether they are now living abroad or still travelling. Roam Like At Home services are provided on a short term basis, and they're not provided for persons living abroad.
Thanks for giving us some feedback MisterW! We're always looking to improve our services, and i'll pass this on to the relevant department to look into. Our Facebook, Twitter and Forum are communication platforms, however, if you require a more instant response take a look at our Live Chat facility at www.plus.net.
