Hi cheers for that I will try another Samsung first as I have 4 spare ones.

no 4g

When I put his o2 sim card into my phone it connects ok, when I put my talkmobile sim card into his phone it connects ok. When we swap the cards back mine connects in my phone, his does't. this does not make any sense to me at all.

Spoke to soon it's not working again so I spoke to cs at o2 they did't know what to do, so he came over to my house and we swapped sim cards in both phones and could connect straight away but when we swapped back his phone back to not connecting.

Hi all and thanks for all your help I have just had a phone call from my son and he says it's all working again now I pressed him on what he did to get it going again but he told me 100% he did nothing to his phone he was just reading the news and decided to have another go and he got straight in. This is a complete mystery, and he would have told me if he did anything to the phone. thanks again all. bj

Just found out the problem phone is on O2 but must stress he can connect to my dvr all ok through the same Samsung DDNS that he uses for his own dvr. and both sites have worked fine for over 3 years.

Thanks James will look into this when I find out who they use. cheers

Ok cheers for that but just trying to find out why it's stopped working after 3 years, but will find out more tomorrow when I know what networks they are both on. cheers

I havn't got a problem please read the 1st post

I m on talkmobile not talktalk it is part of vodaphone

Thanks, I am on talkmobile thats ok, wife is on 3 thats ok, don't know what my daughter or her husband is on yet. but as I said strange it's just stoped working it's been ok for over 3 years. cheers

Thanks for that I will be on the case tomorrow, but I have just found out by my wife that our daughter is on a different mobile network than her husband, so that might be the answer just strange it has been working ok for over 3 years. thanks again.

O yes just figured out what you mean I don',t know who their mobile isp is I will find out if they are the same one tomorrow and will re post, when you think about it the only thing different could be their sim card provider. cheers

Sorry I really don't know what you mean, they are husband and wife. Wife has talk talk isp the same as him both using ipolis apps on their iphones both have the same settings in the ipolis apps sit together in their home both on 4g wife can connect he can't.

I connect through virgin media to samsung ddns then to his talk talk router, his wife's isp is the same as his isp talk talk, same ddns settings in the app and she can connect all ok just his phone.
