I want to advertise without SDK

Hi all, I am going to advertise my app but the app is already live on App Store and Google Play Store. Which platform can let me advertise immediately without editing my app and submit again.
The current platforms that I searched: AppBrain, iAd, Facebook
Thanks for advice

IF you are using Mopub’s mediator, you can use the following without updating the app:
InMobi, Leadbolt, LifeStreet, Millinel Media, Jumptap, Tapit, Smaato, and any others that use HTML tags. You might be able to with Admob’s mediator also
