¶1for the Court:
¶2¶ 1. While incarcerated, Kristi Fulgham had access to a cell phone and charger, which she provided to an inmate in the Oktibbeha County Jail. Fulgham subsequently pleaded guilty under a statute that prohibits “any ... person” from “fur-nishfing], attempting] to furnish, or assisting] in furnishing to any offender ... an unauthorized electronic device.”
¶3FACTS
¶4¶ 2. In August 2004, Fulgham was incarcerated on a charge of capital murder when she was caught allegedly furnishing a cell phone and charger to another inmate. Fulgham pleaded guilty to furnishing an unauthorized electronic device to an inmate. Fulgham was sentenced to eight years.
¶5¶ 3. Fulgham timely filed a petition for post-conviction relief in the trial court and challenged her guilty plea. Fulgham argued that the statute is unconstitutionally vague, and that she had pleaded guilty to a crime for which she cannot be convicted. She also argued that her counsel was inef*700fective for failing to challenge the constitutionality of the statute.
¶6¶ 4. Without a hearing, the trial court issued an order denying post-conviction relief. The court held that she had waived the right to question the statute’s constitutionality by pleading guilty, and it found the statute was not unconstitutionally vague.
¶7DISCUSSION
¶81. Whether Fulgham’s claim is procedurally barred.
¶9¶ 5. Under Mississippi’s Uniform Post-Conviction Collateral Relief (PCR) Act, Fulgham has the right to file a petition for post-conviction relief challenging the constitutionality of the statute under which she was convicted and sentenced.
Failure by a prisoner to raise objections, defenses, claims, questions, issues or errors either in fact or law which are capable of determination at trial and/or on direct appeal, regardless of whether such are based on the laws and the Constitution of the state of Mississippi or of the United States, shall constitute a waiver thereof and shall be procedurally barred, but the court may upon a showing of cause and actual prejudice grant relief from the waiver.3
¶10¶ 6. Our caselaw clearly establishes that this procedural bar cannot be applied in the face of “errors affecting fundamental rights,” because such a violation “is too significant a deprivation of liberty to be subjected to a procedural bar.”
¶11II. Whether Mississippi Code Section 47-5-193 is unconstitutionally vague.
¶12¶ 7. Fulgham argues that the version of Mississippi Code Section 47-5-193 in force at the time of her guilty plea was facially vague, that is, the vagueness was apparent from the words of the statute.
¶13¶ 8. As previously noted, an unconstitutionally vague statute violates the Due Process Clause of the Fourteenth Amendment to the U.S. Constitution.
¶14¶ 9. As previously noted, Fulgham asserts the statute is facially vague, while the State argues that we should analyze whether the statute is constitutional as applied to Fulgham’s conduct. The U.S. Supreme Court’s jurisprudence has been rather obscure as to when courts should engage in an as-applied analysis versus a facial analysis when reviewing a statute for vagueness.
¶15¶ 10. In U.S. v. National Dairy Products, the parties challenged a criminal statute “on its face” for vagueness, while the Government argued the statute was constitutional as applied to the alleged conduct.
¶16¶ 11. In Village of Hoffman Estates, the Court set forth a test governing a facial challenge to an allegedly vague statute.
¶17¶ 12. In Kolender v. Lawson, the Court used a more stringent vagueness test to strike down an antiloitering statute as being subject to arbitrary enforcement.
¶18 ¶ 13. The Fifth Circuit Court of Appeals has interpreted the Supreme Court’s precedent to require the following steps in a vagueness challenge: 1. The court must consider whether the statute affects a constitutional right.
¶19¶ 14. We agree with the Fifth Circuit’s interpretation of the vagueness doctrine *703and apply it to this case. At the time of Fulgham’s offense, Mississippi Code Section 47-5-193 provided that:
It is unlawful for any officer or employee of the department, or any county sheriffs department, of any private correctional facility in this state in which offenders are confined or for any other person to furnish, attempt to furnish, or assist in furnishing to any offender confined in this state any weapon, deadly weapon, unauthorized electronic device or contraband item. It is unlawful for any person to take, attempt to take, or assist in taking any weapon, unauthorized electronic device or contraband item on property belonging to the department which is occupied or used by offenders, except as authorized by law.32
¶20We note that the statute in effect in 2004 contained no definition for “unauthorized electronic device.”
¶21¶ 15. First, we must determine whether the statute affects a constitutionally protected right. Fulgham does not argue that the statute affects any constitutional right, and we find that it does not. Therefore, we apply the statute to Fulg-ham’s conduct to determine whether she had notice of what conduct was prohibited and whether law enforcement had definite standards to avoid arbitrary enforcement.
¶22CONCLUSION
¶23¶ 16. This Court remands for an evi-dentiary hearing on (1) whether Fulgham had notice that a cell phone and charger constituted an “electronic device,” and if so, (2) whether she had notice that they were “unauthorized,” and (3) whether law enforcement had definite standards to avoid arbitrary enforcement. This inquiry will allow the trial court to determine whether the statute is unconstitutional as applied to Fulgham’s conduct and whether relief should be granted.
