Apple recently released its iOS 12.1.3 update, shortly after which many iPhone users in the US on the Sprint and AT&T network began to face mobile data connectivity issues. Many users have taken to Reddit to report the issue of not having very good data connectivity or having very poor data connectivity after upgrading.
The root cause of the problem remains unknown as of now. However, according to previous reports, some users faced similar connectivity issues when the company released its iOS 12.1.2 update last month.
It appears that Sprint is already aware of the issue as they recently said in a tweet that they know that some of their customers using an iPhone X, iPhone XS, and iPhone XR are experiencing service issues and that they are currently working to resolve this issue as as fast as possible.
Some Sprint customers with iPhone X, iPhone XS, and iPhone XR are experiencing service issues. Our teams are working to resolve the issue as quickly as possible.

The tweet makes it look like there is a problem with the telecom service provider network and not with the latest iOS update. However, since this is also an issue for some AT&T customers, it looks like it could be due to the new update. Apple has not released any statement regarding this issue.
Apple Support through its own Twitter account has also responded to a few users, stating that they need more details about the problem, to find out what is causing the problem.

To recall, Apple began rolling out the iOS 12.1.3 update for all iPhone and iPad users on January 23. The update was approximately 334.5MB in size, which could be larger depending on the latest released update.
The update brings some major bug fixes for issues affecting messages, photos, CarPlay, and the audio distortion issue on the new iPad Pro (2018).
