Push notifications only work on WiFi when cellular data is OFF

Your problem relays on the fact that Comcel has an issue with push notifications, when you have your phone connected to both wifi and their network, your phone prioritizes the 3G network over wifi to save energy therefore notifications depend on the mobile network not the wifi. As there is an issue with Comcel's network notifications get delayed or never arrive that's your problem and you are not alone, we all have the same problem with Comcel. When you connect only over wifi the notifications work with the wifi network and therefore your phone doesn't connect to Comcel, as a result they work perfectly.

Hey I am been having the same issue since I got my first iPhone 3 years ago with Comcel. It's been three phones a 3G, a 3Gs and a 4 and the issue unfortunately continues. I restored my phones several times in addition of taking them to Comcel's technical service with no results at all. After some research I concluded the problem has to do with Comcel because when I travel abroad the phone works flawlessly with foreign carriers and it also works perfectly when connected to wifi only. In addition to these my mom, my brother and my fiends have the same situation and they are all Comcel, not even my iPad 3G works ok with them. I have checked several sites and found that the issue has to do with Comcel's IP protocols, therefore and unfortunately for us it is a problem on their end and it seems there is no solution in the short run which means delayed notifications and most of Apple Essential services not working for us. I have contacted Comcel three times and they have only responded that their network is fine and that I am free to start legal actions against them. And so I have dicided to do exactly that, we are consumers protected by law and we are not receiving the service that was offered to us and that we are paying monthly. Therefore we are honoring the contract by paying for the services, the ones breaking the contract and the law are them. I need to get as many people to declare against them in a process in the Super Intendencia de Industria y Comercio to get them to fix the service they are supposed to supply, I am not interested in getting any monetary compensation from them I only want them to fix the issue and provide the service as they should. If you want to join please let me know, it is the only way to get them to fix the issue.

Well Juan Pablo, actually I have already presented the case and they are supposed to respond by Wednesday next week. Once they respond, the case will be submitted to La Superintendencia de Industria y Comercio and they will decide what sanctions or measures shall be taken, let's hope they do. I don't now the time frame that the Superintendencia will take to respond the case. So let's hope it goes through in less than a month and that they actually force Comcel to solve the issue.

My advise to you is to also present your case. The more people that complaints against Comcel the more chances we have to force them to solve the issue. The protocol to present the complaint consist of firs filing the complaint with Comcel you can do it by sending an email to Comcel's Costumer Service Department their email is servicioalcliente@comcel.com.co. You have to be the owner of the line and once you present the complaint Comcel will have 15 working days to respond to it. They will probably respond that their network is fine and that push notifications are not supposed to be instantanious, which is totally false. Once they respond you the law grants you the right to present a Recurso de Reposicion y en Subsidio Apelacion in which you have to respond why you don't agree with Comcel's response. You have 5 working days to present it after they respond you. Once you do this, they will have again 15 working days to respond, and after this the case will be submitted to the authorities which take the final decision. Good luck and I will post something once I get the official reply of the authorities.

Im glad to see this im Comcel too and i've the same problem as you... i had a call today cuz i called yesterday and told them about the problem... he said that they are having troubles to communicate to the Apple PUSH servers and they are having a lot of calls, ppl has the same problem... so he said they are working on that but if you said they are having the same issue since the first iPhone then i guess they are not resolving that issue... im wondering if this happens with Tigo and Movistar too... have you test it on these carriers??

Carrier: COMCEL / iOS 5

This notification problem only happens with Comcel, I now for shore that that in Tigo the notification work perctly. I now this beacuese my iPhone is on Comcel and my Cusen is on Tigo and we started to meke several test and the result were increadeble, with comcel any app that works with notification the mesage arrive beetwen 15 to 30 minutes late, but with tigo the notifications were instantly. I know for shore that when my contract ends i'm gonna ask them to unlock my iPhone and then i'm going to change to Tigo.

Although it is to early to define anything, the push notifications have been working the whole day and I must say it is the first time since I got my first iPhone back in 2008. I don't want to to get into concluding anything but has anyone else noted this? I have done tests throughout the day and I must say I am surprised with the results, please let me know if you have noted any improvements.

UPDATE: the service only worked on Wednesday but it is no longer working. I don't know if Comcel is fixing the issue finally, I hope they are but I will continue with my legal actions against them. It would be good if all of you present your cases to the Superintendencia the more people that declare against them the more likely that they will be sanctioned and forced to fix the issue.

I have this problem, too. My carrier is KT (Korea Telecom, olleh, KTF). But rare. I think this is APN Server problem of Carriers. I found this problem occurs iOS 4+ only.(iOS 3 was normal) Apple needs to investigate this issue with carriers.

I called to Comcel and they said they cant tell me an expecified date of the fixing of the problem thats means the problem will not be fixed by now... i like Comcel network but if they dont fix this i will quit comcel and go to another carrier like Tigo or Movistar wich they have the notifications working

With all due respect to all of you Comcel is a terrible company. They might have the best coverage and the best 3G speeds, but they have the worst costumer service and business practices I have seen. And all of these will not change until you people claim your consumer rights. Comcel has been selling the iPhone since 2008 without the required infrastructure to work with the iPhone and most especifically Push Notifications. I basically have been paying the thiefs 220,000 pesos a month since I got the 3G back in 2008 and for all of these time they haven't delivered an appropriate service so the iPhone can work correctly. I really was indifferent to this issue until this year when I decided to make them fix the issue. I have checked this issue several times with my law teacher at college, and he is an outstanding lawyer, and he says that we have all the odds to win this case and force them to fix the issue. So please, start presenting complaints in the Superintendencia, this is the only way to get to fix the issue.

2 weeks ago I bought the new comcel's Iphone 4S, and like you said, push notifications don't work as they should; i get messages 10 or 20 minutes late and sometimes I don't even get them. It's a shame because I bought a 2 year contract phone that i will have to use without it working the way it should do. I started complaining right away, but always the same answer: "restore the phone to factory settings", "reset network settings, etc. None of these have worked, I even started thinking it was a hardware problem and also It came to my mind that maybe thats just the way push notifications work. But to my surprise my friends Iphones in other carriers, (tigo, movistar) worked like a charm, and also my phone worked perfectly on wifi with cellular data off.

I really don't know what to do but I'm dissapointed with comcel, apple shouldn't be selling iphones through this carrier. My main problem is that this comes since apple lauched push notifications(problem that I was unfortunately unaware about), so comcel doesn't seem to be worried or working on it.

Please let me know how to help you to declare against Comcel, cuz I tire of not geting any answares.

Is this an old problem? cuz they said they was fixing it...

I have the same problem with Comcel, which also means almost never being able to receive FaceTime calls.

Any concrete news on when this will be fixed???
